    Science Alert ^ | 17 April 2024 | MICHELLE STARR
    You never really know what you might find hiding in your own backyard, especially if those things are particularly adept at escaping detection. Just 1,924 light-years from the Solar System, in the constellation of Aquila, astronomers have just discovered a black hole. And it's not just any black hole. Named Gaia BH3, or BH3, the object is the most massive stellar-mass black hole we've ever spotted in the Milky Way, clocking in at a hefty 33 times the mass of the Sun. It's the second-closest black hole we've found to our home-world, and it's just hanging out, quietly in space,...

    Explanation: Not one, but two comets appeared near the Sun during last week's total solar eclipse. The expected comet was Comet 12P/Pons-Brooks, but it was disappointingly dimmer than many had hoped. However, relatively unknown Comet SOHO-5008 also appeared in long duration camera exposures. This comet was the 5008th comet identified on images taken by ESA & NASA's Sun-orbiting SOHO spacecraft. Likely much smaller, Comet SOHO-5008 was a sungrazer which disintegrated within hours as it passed too near the Sun. The featured image is not only unusual for capturing two comets during an eclipse, but one of the rare times that...

    From the Sciences and Cosmology web page: "Want me to tell you something that will blow your mind or make you lose sleep? Well, look at this picture. Each of those dots you see is a GALAXY... And each GALAXY has roughly 100BILLION STARS. Also, each STAR has at least 1 PLANET. Now how many galaxies do you think there can be in that picture? And this is just a photograph of a very little parcel of the universe. This makes me lose sleep, thinking about how so insignificant we really are. Lol."

    Methane plumes are detected by plane at a Georgia landfill surrounded by homes. Photo courtesy of Carbon Mapper April 16 (UPI) -- Far more methane, a potent greenhouse gas, is being released from landfills and oil and gas operations around the world than governments realized, recent airborne and satellite surveys show. That's a problem for the climate as well as human health. It's also why the U.S. government has been tightening regulations on methane leaks and wasteful venting, most recently from oil and gas wells on public lands. The good news is that many of those leaks can be fixed...
  • First-Ever 2D Single-Atom Layer of GOLD Created Using 100-Year-Old Japanese Etching Technique

    The Debrief ^ | APRIL 16, 2024 | CHRISTOPHER PLAIN
    Research scientists from Linköping University (LiU) in Sweden say they have created the first two-dimensional single-atom layer of gold using a technique perfected by Japanese smiths over 100 years ago. Dubbed “goldene” in reference to the popular single-atom carbon material graphene that essentially kicked off the 2D materials revolution, the breakthrough material could possess a large number of exotic properties like those found in other single-atom 2D materials. The researchers behind the first-ever accomplishment also say they believe goldene could also offer several immediate applications. These include new methods for harvesting energy, catalysis for hydrogen generation, carbon conversion, water purification,...
  • Astronomy Picture of the Day - Filaments of the Vela Supernova Remnant

    Explanation: The explosion is over, but the consequences continue. About eleven thousand years ago, a star in the constellation of Vela could be seen to explode, creating a strange point of light briefly visible to humans living near the beginning of recorded history. The outer layers of the star crashed into the interstellar medium, driving a shock wave that is still visible today. The featured image captures some of that filamentary and gigantic shock in visible light. As gas flies away from the detonated star, it decays and reacts with the interstellar medium, producing light in many different colors and...
  • Astronomy Picture of the Day - The Cigar Galaxy from Hubble and Webb

    Explanation: Something strange happened to this galaxy, but what? Known as the Cigar Galaxy and cataloged as M82, red glowing gas and dust are being cast out from the center. Although this starburst galaxy was surely stirred up by a recent pass near its neighbor, large spiral galaxy M81, this doesn't fully explain the source of the red-glowing outwardly expanding gas and dust. Evidence indicates that this material is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. In the featured images, a Hubble Space Telescope image in visible light is shown...

    International Thinktank Applied Physics (AP) has released its “Warp Factory” simulator and toolkit to help scientists and engineers move closer to building a real-world Star Trek-style warp drive. Having already established itself in the nascent field of warp mechanics with the previous release of its “physical warp drive” design in 2021, AP is now offering its expertise to the broader community to advance the development of existing and future warp drive concepts. The Public Benefit Corporation is also putting its money where its mouth is by offering warp field theorists a chance at $500,000 worth of grant money, a commitment...
  • Astronomy Picture of the Day - How a Total Solar Eclipse Ended

    NASA ^ | 14 Apr, 2024 | Video Credit & Copyright: David Duarte
    Explanation: How does a total solar eclipse end? Yes, the Moon moves out from fully blocking the Sun, but in the first few seconds of transition, interesting things appear. The first is called a diamond ring. Light might stream between mountains or through relative lowlands around the Moon's edge, as seen from your location, making this sudden first light, when combined with the corona that surrounds the Moon, look like a diamond ring. Within seconds other light streams appear that are called, collectively, Bailey's beads. In the featured video, it may seem that the pink triangular prominence on the Sun...

    Explanation: Only those along the narrow track of the Moon's shadow on April 8 saw a total solar eclipse. But most of North America still saw a partial eclipse of the Sun. From Clearwater, Florida, USA this single snapshot captured multiple images of that more widely viewed celestial event without observing the Sun directly. In the shade of a palm tree, criss-crossing fronds are projecting recognizable eclipse images on the ground, pinhole camera style. In Clearwater the maximum eclipse phase was about 53 percent.

    Explanation: Baily's beads often appear at the boundaries of the total phase of an eclipse of the Sun. Pearls of sunlight still beaming through gaps in the rugged terrain along the lunar limb silhouette, their appearance is recorded in this dramatic timelapse composite. The series of images follows the Moon's edge from beginning through the end of totality during April 8's solar eclipse from Durango, Mexico. They also capture pinkish prominences of plasma arcing high above the edge of the active Sun. One of the first places in North America visited by the Moon's shadow on April 8, totality in...

    NASA ^ | 11 Apr, 2024 | Image Credit & Copyright: Xiaofeng Tan
    Explanation: Start at the upper left above and you can follow the progress of April 8's total eclipse of the Sun in seven sharp, separate exposures. The image sequence was recorded with a telescope and camera located within the narrow path of totality as the Moon's shadow swept across Newport, Vermont, USA. At center is a spectacular view of the solar corona. The tenuous outer atmosphere of the Sun is only easily visible to the eye in clear dark skies during the total eclipse phase. Seen from Newport, the total phase for this solar eclipse lasted about 3 minutes and...

    Hindustan Times ^ | 11 Apr 2024, 01:54 PM IST | Staff
    A Russian spacecraft, named [Cosmos 2221] came dangerously close to a U.S. satellite, passing within just 10 meters in space. Experts have asserted that the near-miss could have had severe consequences, potentially endangering lives on Earth. NASA's Timed satellite, designed to monitor Earth's atmosphere, narrowly avoided a collision with the defunct Russian spy satellite Cosmos 2221. Colonel Pam Melroy, NASA's deputy administrator and a former astronaut, described the incident as "really scary" for the U.S. space agency. Speaking at the Space Foundation’s Space Symposium in Colorado, Melroy said, “It was very shocking personally and for all of us at Nasa,"...
  • Sheila Jackson Lee Named Head Of Harvard Astronomy Department

    In the wake of claiming the moon is made of gas and the sun is "almost" too hot to get close to, Texas Congresswoman Sheila Jackson Lee has been named the new head of Harvard University's Astronomy Department. The Board of Overseers at the prestigious Ivy League institution was reportedly wowed by Jackson Lee's insights into the cosmos, with the school immediately seeking to get in touch with her about the department head position. "Her knowledge blew us away," said Harvard Interim President Alan Garber. "When she said, 'The moon is made up of mostly gasses. That's why the question...
  • Scientists Create Levitating Graphite Plate For Ultra-Sensitive Quantum Sensors

    Science Alert ^ | April 11, 2024 | DAVID NIELD
    (Okinawa Institute of Science and Technology) Levitation is the kind of superpower many researchers would love to get their hands on. While there are a number of ways to fight the forces of gravity, few are suitable for the kinds of ultrasensitive devices that would benefit from floating untethered in a vacuum. Led by a team from the Okinawa Institute of Science and Technology (OIST) in Japan, a team of researchers have found a way to shield thin wafers of graphite as they hover freely above a grid of magnets, making them far less susceptible to currents that interfere with...
  • Thousands of Meteorites Are Vanishing in Antarctica. Now Scientists Have Revealed Why [Guess!]

    The Debrief ^ | APRIL 10, 2024 | CHRISTOPHER PLAIN
    A team of European researchers says that hundreds of thousands of meteorites, which may provide valuable information about the dawn of life on Earth, are disappearing from Antarctica at an alarming rate. Based on their research, the scientists behind the alarming findings say that as many as three-quarters of the approximately 300,000-800,000 meteorites resting on the surface of the Antarctic ice sheet could be lost by 2050. Published in the journal Nature Climate Change, the research says the culprit behind the wholesale disappearance is the steady rise in global temperature. “For every tenth of a degree of increase in global...

    “Well, a testicular eclipse is probably not something you had on your bingo card, but here we are. As you likely know by now, Monday was the big day for the Solar eclipse, and many states in the US were in the path of the “total eclipse,” as were other countries around the world. In fact, folks near Torreón, Mexico, got to experience “totality” for one of the longest periods of time, lasting 4 minutes and 28 seconds, according to NASA. Wikipedia explains that the solar eclipse of April 8, 2024, was a total solar eclipse visible within a band...

    Social media users trashed Rep. Sheila Jackson Lee, D-Texas, after she turned her gaffe about the moon being "made of gases" into a slam of Republicans on social media Tuesday. Reacting to the backlash she received for telling school children that the moon is made of gases ahead of Monday’s eclipse, the lawmaker said that her Republican critics are hounding her because they have a "lust for stupidity." She gave a speech at Booker T. Washington High School in Houston on the day of the eclipse, telling an assembly of students, "Sometimes, you need to take the opportunity just to...

    While Democrats and leftist alarmists decry conservatives for supposedly peddling "misinformation" about "the Science™" related to climate, COVID, and genders (there are two, FYI), their own Rep. Sheila Jackson Lee of Texas is out and about telling constituents some real whoppers about the solar eclipse.
