Lyrid Meteor Shower 2023: Viewing Opportunities and What to Expect

Get Ready for the 2023 Lyrid Meteor Shower: A Celestial Spectacle in April 

The Lyrid meteor shower is an annual event that occurs between April 16-25 every year. The peak of this year's shower will be on the night of April 22, 2023. According to NASA meteor expert Bill Cooke, the viewing opportunities for the 2023 Lyrids will be favorable, as the waxing crescent moon will be just 6% illuminated on the night of the peak.

While the peak viewing time for most meteor showers is before dawn, the Lyrids will become visible beginning at about 10:30 p.m. local time, Cooke told Space.com. The shower is known for its luminous dust trains which can be observed for several seconds, making it a fascinating celestial spectacle.

The Lyrids are associated with Comet Thatcher, a long-period comet that orbits the sun every 415.5 years. It last reached its closest approach to the sun in 1861. The meteor shower occurs when the Earth passes through the trail of dust left behind by the comet.

The average Lyrid shower produces 15 to 20 meteors per hour. However, some years, the Lyrid meteor shower intensifies and can produce up to 100 meteors per hour in what's called an "outburst." It is difficult to predict exactly when these outbursts will occur, as there is no clear periodicity in the data. While there is an average of 30 years between these outbursts, the actual number of years between the events varies, according to Cooke.

In order to view the Lyrids, it is recommended to find a location away from city lights and allow your eyes to adjust to the darkness for at least 20 minutes. Look towards the radiant, which is the point in the sky from which the meteors appear to originate, in the constellation Lyra. However, the meteors can appear anywhere in the sky, so it is best to keep an open view.

Overall, the Lyrid meteor shower is a fascinating event that showcases the beauty and wonder of our universe. With favorable viewing conditions and the possibility of an outburst, it is an event not to be missed by stargazers and astronomy enthusiasts alike.

Elon Musk's SpaceX Delays Launch of Powerful Starship Rocket Due to Technical Issue

SpaceX’s much-awaited launch of the Starship, the world’s most powerful rocket, has been delayed for 48 hours due to a frozen “pressurant valve.” The rocket was built by Elon Musk’s SpaceX company, and the uncrewed mission was aborted just minutes before its launch on Monday from Boca Chica, Texas. Musk tweeted that the Starship could be launched anytime later this week. The rocket is about 120m (400ft) high, and has more thrust than any of the previous rockets, with the aim of sending the upper stage of the rocket to complete one round around the globe.

Before the launch was delayed, Musk urged everyone to calm their expectations, saying that it is common for a rocket to go through some hurdles initially. At a Twitter space event, he said, “It’s the first launch of a very complicated, gigantic rocket, so it might not launch. We’re going to be very careful, and if we see anything that gives us concern, we will postpone the launch.”

Thousands of people crowded the coastal locations on the Gulf of Mexico to witness the Starship launch. Musk, the US entrepreneur and owner of the SpaceX company, is seeking to conquer the rocket business with Starship. The rocket is designed to be fully and rapidly reusable so that it could fly people and satellites into orbit several times in a day similar to a jet crossing the Atlantic.

Previously, the top portion of Starship was tested on short hops, but for the first time, it would be sent with its lower stage. In February, the massive booster, called Super Heavy, fired while it was attached to its launch mount. However, the engines at that time were controlled to half their capability.

If everything goes as planned for the other launch this week, SpaceX will go ahead with 90% thrust, such that the stage would provide almost 70 meganewtons which is equal to the force required to push about 100 Concorde supersonic airliners to blast off.

Starship will launch and move down range across the Gulf with 33 methane-fuelled booster engines, at the bottom, powering the rocket for two minutes and 49 seconds. When the rocket separates into two halves, the top segment of the ship will carry on with its engines for six minutes and 23 seconds more. It should be flying over the Caribbean by this time while floating in space for over 100km (62 miles) above the surface of the Earth.

SpaceX desires that the Super Heavy booster flies back near the coast of Texas and vertically hover above the Gulf’s waters, and then the rocket will drop into the water and sink. Starship is expected to re-enter the planet’s atmosphere after completing one circuit of the planet and then lower towards the Pacific, north of the Hawaiian islands. It has a protective tiling to deal with the extreme heat while descending. It will dive into the ocean roughly an hour and a half after its launch.

SpaceX hopes that in the long run, the booster as well as the ship would land in a way for it to be refueled and relaunched. The company has been conducting tests at Boca Chica using different methods to construct steel stages, and various models are waiting to be tested.

The US space agency NASA is among the most interested spectators on Monday as it has offered SpaceX almost $3bn to build an adaption of Starship that will help land astronauts on the Moon.

Musk has plans to travel deeper into the Solar System, said Garrett Reisman, a professor of astronautical engineering at the University of Southern California. The SpaceX advisor and former astronaut told BBC News, “He sees Starship as potentially another giant paradigm shift, an incredible increase in capability, the capability to truly bring people on large scale to Mars.”

Alaskans Stunned by Mysterious Spiral in the Sky

 

Late Friday night, many Alaskans witnessed a strange spiral moving through the sky, which some likened to an alien spaceship or a portal to an alternate universe. However, the truth was far less mysterious. Many on social media speculated that it was rocket exhaust, which was confirmed by Space Physicist Don Hampton, a research associate professor at the University of Alaska-Fairbanks Geophysical Institute.

According to Hampton, the phenomenon was likely caused by the SpaceX Transporter-7 mission, which launched on the Falcon 9 about three hours earlier in California. As the rocket gained altitude, water vapor in the exhaust from the second stage engine froze and caught high-altitude sunlight, creating the spiral galaxy of a display that many Alaskans witnessed. The payload on the rocket was 51 satellites, which were on their way to orbit.

Despite the explanation, the sight was still eerie and amazing, and a brilliant aurora only added to the spectacle. As the rocket did a pass-by over Alaska, it stunned many night-watchers, creating a moment that will undoubtedly be remembered for some time. While some may have been disappointed that the phenomenon wasn't an alien spaceship or a portal to another dimension, it was still an incredible sight and a testament to the amazing feats that modern technology can accomplish.

Oldest bat skeletons at 52 million years old reveal a strange story

 

The oldest bat fossil found to date would have flown around what is now the US state of Wyoming 52 million years ago. But how did it find food without echolocation? (Source: Royal Ontario Museum)

The oldest bat skeletons in the world have been identified as a new species, helping scientists fill in the spotty fossil record of these flying mammals and providing new clues about how they evolved. Both skeletons were recovered from an ancient lakebed in southwestern Wyoming, a site that preserves an entire subtropical lake ecosystem and surrounding forest from about 52 million years ago.

The newly discovered bat, Icaronycteris gunnelli, weighed only about 25 grams, roughly as much as five marbles. It had already evolved the ability to fly and likely had developed the capacity to echolocate. The small bat probably lived in the trees surrounding the lake, flying over the water to hunt insects, says Tim Rietbergen, an evolutionary biologist at the Naturalis Biodiversity Center in the Netherlands and lead author of the study describing the species in the journal PLOS ONE.

Today bats are among the most successful animals on the planet, with more than 1,400 species accounting for one-fifth of all mammal species. They live on every continent except Antarctica, and they are often critical to ecological stability, providing key functions such as pollination, seed dispersal, and insect population management.

Despite the ubiquitousness of bats, scientists know very little about their origins. The skeletons from Fossil Lake, the name of the preserved lakebed in Wyoming, date to the early Eocene epoch. At that time, global temperatures were on the rise and mammals, insects, and flowering plants were rapidly spreading and diversifying. These bats look remarkably similar to modern bats, with elongated fingers to hold wing membranes.

“The thought is that … bats originated from some sort of small, insectivorous mammals that were probably arboreal,” says Matthew Jones, a paleontologist at Arizona State University and one of the authors of the study. “But there’s a lot of those,” he adds, pointing out that we don’t know which ones may be related to bats. “Most of them are only known from isolated teeth and jaw fragments.”

After bats appear in the fossil record, they quickly spread around the world. The most ancient bat teeth and jaw bones found so far are roughly 55 million years old. Incomplete specimens from Portugal and China predate the newly described skeletons by a few million years. Scientists don’t know where bats first appeared, though it was likely in Europe, Asia, or North America before the animals spread to the Southern Hemisphere.

“It’s kind of a mystery,” says Alexa Sadier, an evolutionary biologist at the University of California, Los Angeles, who was not involved in the new study. “We don’t have any transitional forms.”

Rietbergen first saw one of the skeletons of Icaronycteris gunnelli in 2017 when he was scrolling through Facebook. “I was like, hmm, this looks a little bit different,” he says.

After asking for some measurements of the fossil, which had been found at a private quarry and was listed for sale, he reached out to Nancy Simmons, a bat expert at the American Museum of Natural History. She agreed with him that it looked like a new species, and AMNH bought the fossil for its collections.

In addition to analyzing the new fossil, the study team reexamined bat skeletons that were already in museum collections. They found another fossil of I. gunnelli that had been acquired by the Royal Ontario Museum in 2002 and was originally classified as the related species.

The two skeletons look similar to modern bats, but there are subtle differences. “One thing that stood out for me in the first place,” Rietbergen says, “was the robustness of the bones, especially the hind limbs.”

Juice: The Billion-Pound Probe Blasting Off to Hunt for Extraterrestrial Life on Jupiter's Icy Moons

The ice on Europa, one of Jupiter’s moons, covers vast oceans of liquid water – and one of our best hopes of finding extraterrestrial life.NASA/JPL-CALTECH/SETI INSTITUTE

 In a few days, the Jupiter Icy Moons Explorer (Juice) will be launched on an eight-year mission to find signs of life on the icy moons of distant Jupiter. Juice will explore the greatest reserves of water that exist on worlds far from Earth, in deep space and in orbit around the giant planets Jupiter and Saturn. The mission aims to find places around Jupiter where life could have started and to discover more water than on Earth.

Juice will focus on Ganymede, the largest moon in the solar system. After a series of visits to Callisto and Europa, Juice will enter into a permanent orbit around Ganymede in 2034. It will be the first time a spacecraft has ever held an orbit around a moon other than our own.

Nasa’s Europa Clipper, on the other hand, will take a shorter route using flybys of Earth and Mars, to arrive at Europa in April 2030. The US spacecraft will focus on Europa and is scheduled to make 50 close approaches of the moon, sweeping a few hundred miles over its surface to try to spot areas that could support life.

If these missions find that life has evolved twice, separately, in our own solar system, it would indicate that it is likely to be widespread throughout the galaxy. Results could be revolutionary.

Getting there is a different matter, however. Journeys to Mars take about eight months. By contrast, Juice will take about eight years to reach Jupiter, a journey that will require a series of flybys of Earth and Venus to keep it up to speed.

Juice’s blast-off will be watched with bated breath by the scores of European scientists who have collaborated on the project and who will watch as it is carried aloft on an Ariane 5 launcher, the same rocket that placed the James Webb space telescope on a perfect trajectory on Christmas Day 2021. They will be hoping for a repeat performance.

In conclusion, Juice's mission to explore the icy moons of distant Jupiter will open up a new chapter in the hunt for extraterrestrial life. If successful, the mission could reveal that life exists not only on Earth but also on other worlds in our solar system. With close collaboration between the European Space Agency (Esa) and Nasa, the two missions, Juice and Europa Clipper, could yield revolutionary results that would change our understanding of the universe.

Elon Musk Opens Up: The Rollercoaster Ride of Owning Twitter

 

Elon Musk has revealed in a recent interview with the BBC that owning Twitter has not been an easy experience, contrary to popular belief. Musk opened up about his time managing the platform and how the media in the US and the UK have been very harsh about him, while in certain countries, the media does not dare to go after the powerful.

During the interview, Musk took questions from listeners and revealed that his hand was forced into buying Twitter, despite knowing it was going to be a problem child for him. He also discussed the cash flow problems that existed at Twitter when he took over, which led to his decision to lay off employees at the social media startup.

Musk was also questioned about misinformation on the platform and whether Twitter is sufficiently policed. He became defensive, challenging the interviewer, "Who's to say what's right and wrong?" He also claimed that there was no increase in "hateful content" on Twitter since he took charge and asked for an example.

Musk's relationship with the media was also discussed, with him admitting to having an "odd" relationship with it, describing it as "love-hate, perhaps more hate." He believes that it is good to have a free press in which he and other "powerful people" may be written about, but he does not want Twitter to further elevate "some anointed class of journalists" who decide what constitutes news.

In summary, Musk's interview with the BBC shed light on his experiences managing Twitter, including the struggles he faced and his relationship with the media.

Advancing Heart Health in Space and on Earth: Expedition 69's Mission on the International Space Station

 

The SpaceX Dragon resupply ship approaches the station above the Indian Ocean near Madagascar on March 16, 2023.

On Tuesday, the International Space Station Expedition 69 crew members focused their attention on cardiac research in an effort to advance human health both on Earth and in space. The main research objective of the day was the Cardinal Health 2 experiment, which is taking place inside the Kibo laboratory module. This study aims to prevent space-caused heart conditions and Earth-bound cardiac disorders.

Flight Engineers Woody Hoburg of NASA and Sultan Alneyadi of UAE took turns supporting the Cardinal Health 2 experiment, treating engineered heart tissue samples inside Kibo’s Life Sciences Glovebox to help doctors understand gravitational stresses on cardiovascular cells and tissues. Observations from this experiment may lead to potential treatments advancing heart health for both astronauts and Earthlings.

The samples from the Cardinal Health 2 experiment and other experiments will soon be packed inside the SpaceX Dragon cargo craft for analysis by researchers on the ground. NASA Flight Engineers Frank Rubio and Stephen Bowen partnered together to ready the Dragon for its departure on Saturday, April 15, when it will undock from the Harmony module’s forward port at 11:05 a.m. EDT. The duo packed a variety of research gear and station hardware, securely strapping them inside Dragon. The U.S. space freighter will parachute to a splashdown off the coast of Florida several hours later for retrieval by SpaceX and NASA support personnel.

Meanwhile, two cosmonauts continued gearing up for a series of spacewalks set to begin on Tuesday, April 18. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin will work over three spacewalks to maneuver an experiment airlock and a radiator from the Rassvet module to the Nauka science module. The duo spent the day readying their Orlan spacesuits inside the Poisk module, checking for pressure leaks, and installing suit batteries and other components.

At the beginning of the day, Prokopyev took part in a cardiac study with assistance from Flight Engineer Andrey Fedyaev. Fedyaev attached sensors to Prokopyev and photographed the experiment activities that monitor a cosmonaut’s blood circulation in microgravity. Fedyaev then spent the rest of his day on computer maintenance, station window inspections, and a fitness test on a treadmill.

In conclusion, the Expedition 69 crew members aboard the International Space Station are working hard to further our understanding of the impact of microgravity on the cardiovascular system. The research being conducted aboard the station has the potential to improve heart health for both astronauts and people on Earth. Additionally, the preparation for the upcoming spacewalks and the return of the SpaceX Dragon cargo craft demonstrate the constant activity and productivity of the ISS crew.

James Webb Space Telescope Captures Stunning New Details of Cassiopeia A Supernova Remnant

 The James Webb Space Telescope has captured never-before-seen details of the glowing gas and dust of Cassiopeia A, the youngest known supernova remnant in our galaxy. Located 11,000 light-years away in the Cassiopeia constellation, the remnant stretches for 10 light-years and represents a unique opportunity for astronomers to study how stellar explosions occur. The Webb telescope's infrared capabilities allowed it to capture incredible detail that other telescopes had missed. The resulting image has been translated into visible light, revealing warm dust on the remnant's exterior in red and orange hues, while bright pink light and clumps and knots inside the bubble-like structure indicate the material ejected from the exploded star.

The image also captured a bright green loop along the right side of the bubble, which the researchers have nicknamed "the Green Monster." The team is still trying to understand the sources behind all of the different colors in the image, but studying remnants like Cas A can help scientists understand cosmic dust, a building block for stars and planets, and how exploded stars release elements crucial for life.

Danny Milisavljevic, assistant professor at Purdue University and principal investigator of the Webb program that captured the new observations, said, "Cas A represents our best opportunity to look at the debris field of an exploded star and run a kind of stellar autopsy to understand what type of star was there beforehand and how that star exploded." Meanwhile, co-investigator Tea Temim, research astronomer at Princeton University, said, "Compared to previous infrared images, we see incredible detail that we haven't been able to access before."

By understanding the process of exploding stars, scientists are also able to read their own origin story. As Milisavljevic said, "I'm going to spend the rest of my career trying to understand what's in this data set." The insights from Cas A and other remnants like it allow scientists to learn more about how stellar explosions occur and the release of elements crucial for life.
