But the kicker is that this giant void shouldn't exist in the first place. For example, some people have correctly argued that such a void shouldn't exist in the standard model, which is true. Cosmologists have a value, called the Hubble constant, which they use to help describe how fast the universe's expansion is accelerating. The Hubble constant should be the same value wherever you look, whether it's close by or very far away. NASA/JPL-CaltechAstronomers can't agree on what's causing this discrepancy in the Hubble constant, and the contention has become known as the Hubble tension.

The Harvard professor's research is bankrolled by tech tycoons "pissed off" at academia's dogma. But this boundary-pushing is exactly why he's backed Loeb's research. AdvertisementDesch, the astrophysicist from Arizona University, posted a critique of Loeb's work on arXiv alleging "multiple fatal flaws with the manuscript's arguments." Asked whether he no longer believes in a possible technological origin for the meteor, Loeb said they need to investigate further. As he plans more extravagant expeditions to prove the origin of the interstellar meteor, Loeb likens his critics to crows pecking at the neck of an eagle.

Read previewThe supermassive black hole at the heart of our galaxy has a side you've never seen before. A new image reveals powerful magnetic fields swirling around our hometown black hole, which is called Sagittarius A* (pronounced "A-star"). EHT had previously imaged its first black hole, Messier 87, in polarized light as well, though it doesn't look quite as striking:The Messier 87 supermassive black hole imaged in polarized light. EHT CollaborationSince both black holes have similar structures of magnetic fields, despite their immense difference in size, the EHT scientists now suspect that all supermassive black holes might have magnetic structures like this. Bigger black hole breakthroughs may be in storeFurther imaging with new innovative techniques and technologies could reveal even more secrets of supermassive black holes, both big and small.

A North Korean spy satellite was spotted adjusting its orbit in space, experts said. AdvertisementA North Korean spy satellite has made maneuvers in orbit that show it is very much "alive," contrary to previous assessments that suggested it was inactive, experts said on Tuesday. North Korea announced it had launched Malligyong-1 into orbit in November, after two failed attempts. The launches drew condemnation from the US, which viewed them as cover for North Korea testing missile technology. The latest findings come as South Korea warned that Pyongyang could launch a new spy satellite as soon as March, The Korea Times reported.

WHAT ARE THE CAPABILITIES OF NORTH KOREA'S ON-ORBIT SPY SATELLITE? To launch a more-capable satellite, North Korea will most likely need to develop a larger rocket, which it appears to be doing, he said. South Korea's spy agency has said North Korea may have overcome technical hurdles with the help of Russia, which in September publicly pledged to help Pyongyang build satellites. The United States and its allies called North Korea's latest satellite tests clear violations of United Nations Security Council resolutions, which prohibit development of technology applicable to North Korea's ballistic missile programs. "North Korea is no longer shy about testing ICBMs, so no - this really is an SLV," he said.

North Korea said it placed its first spy satellite in orbit on Tuesday. South Korea's military said North Korea's military reconnaissance satellite was believed to have entered orbit, but it would take time to assess whether it was operating normally. Critics have said the pact weakened South Korea's ability to monitor the North's near the border while North Korea had violated the agreement. South Korea said it was suspending a clause in the agreement and resuming aerial surveillance near the border. North Korea had notified Japan of a satellite launch after two failed attempts to put what it called spy satellites into orbit this year.

CNN —Two powerful NASA telescopes have detected the oldest and most distant black hole ever found. “We needed Webb to find this remarkably distant galaxy and Chandra to find its supermassive black hole,” said lead study author Akos Bogdan, in a statement. Potential black hole theoryTypically, black holes located at the centers of galaxies only have about 0.1% the mass of the stars within their host galaxy. The unusual black hole could be an “Outsize Black Hole” that formed when a huge cloud of gas collapsed, as theorized in 2017 by Priyamvada Natarajan, a coauthor on both studies and the Joseph S. and Sophia S. Fruton professor of astronomy and professor of physics at Yale University in New Haven, Connecticut. “We think that this is the first detection of an ‘Outsize Black Hole’ and the best evidence yet obtained that some black holes form from massive clouds of gas,” Natarajan said.

In another two of the cases, Cendes noticed the black holes peaking, then fading, then turning on again. Everything we know about accretion disks may be wrongThe findings could mean we need to rethink how black holes swallow up stars, Cendes said. The new findings suggest astronomers will have to rethink the relationship between stars and black holes.

When scientists switched on the instrument aboard a new satellite this summer, they got a preview of what will soon be the nation’s first continuous record of air pollution. The satellite will stay parked above North America and provide scientists with hourly daytime updates on air pollution nationwide. The satellite instrument, called TEMPO, will be able to measure several other pollutants as well. The images come during a summer of exceptionally bad air quality for the United States, with smoke from wildfires blanketing multiple cities and regions. But even before this summer, over the past decade or so, the gains in air quality Americans have enjoyed since the passage of the Clean Air Act in 1970 had started to plateau.

Neptune’s disappearing clouds linked to solar cycle
  + stars: | 2023-08-22 | by ( Kristen Rogers | ) edition.cnn.com   time to read: +6 min
The findings are “extremely exciting and unexpected, especially since Neptune’s previous period of low cloud activity was not nearly as dramatic and prolonged,” Chavez added. The findings also contradict the idea of the clouds being affected by Neptune’s four seasons, which each last about 40 years. Additionally, Neptune storms rising from the deep atmosphere do influence the planet’s cloud cover — but aren’t related to clouds formed in the upper atmosphere. That variable could interfere with studies looking at correlations between photochemically produced clouds and the solar cycle. More research could also suggest how long the near absence of clouds on Neptune might last.

CNN —The Luna 25 spacecraft reported an “emergency situation on board,” Russia’s space agency, Roscosmos, said on Saturday. Russia’s Luna 25 lander mission marked the country’s first attempt at landing a spacecraft on the moon since the Soviet era. The last lunar lander, Luna 24, landed on the lunar surface on August 18, 1976. Luna 25’s trajectory allowed it to surpass India’s Chandrayaan-3 lunar lander, which launched in mid-July, on the way to the lunar surface. Safely landing a spacecraft on the lunar surface would mark a huge step for Russia’s space program.

It was not until 2013 that it became the first South Korean rocket to place a satellite in orbit. SPACE CENTRES Russia also helped South Korea build its Naro Space Center while training and launching the first South Korean astronaut on a mission to the International Space Station. In his first summit with former U.S. President Donald Trump in 2018, North Korean leader Kim Jong Un promised to dismantle Sohae, but as talks stalled, North Korea expanded the site. North Korea faces the same challenges, and must avoid flying over South Korea. “The road from South Korea to space has opened now,” President Yoon Suk Yeol said after the 2022 Nuri launch.

This dying red giant had only recently mysteriously dimmed its shine after an enormous explosion. It is expected to explode into a supernova visible from Earth, though likely not for thousands of years. The red giant — a star not far from death — is now shining about 50% brighter than it usually would, scientists said. Scientists are keeping a close eye on Betelgeuse, as this red giant is a dying star that is close to turning supernova. Betelgeuse could burst into a supernova visible from Earth — one dayA pre-supernova star, called a Wolf-Rayet star, 15,000 light-years away in the constellation Sagittarius.
As the star grew, its surface reached the orbit of the doomed planet, with mayhem ensuing. Red giant stars can swell to a hundred times their original diameter, engulfing any planets in their way. This planet, perhaps a few times bigger than Jupiter, orbited its star in less than a day at a distance closer than Mercury, our innermost planet, orbits the sun. Even before it is engulfed whole, our data provides evidence that the planet tries to rip out the star's surface layers with its own gravity. But the star happens to be a thousand times more massive so the planet can't do much and eventually makes the plunge," De said.
Astronomers discovered a distant star swallowing a planet for the first time ever. Swallowing the planet whole produced a burst of energy that expelled the star's outer layers, causing it to expand and brighten rapidly. Except for a veneer of dust, the star pretty much looked the same as it had before, one year after devouring its planet. The distant planet that just got absorbed by its star was about the size of Jupiter, which is more than 1,300 Earths. (It later turned out, this pre-eruption dust was material from the planet skimming the atmosphere of the star as it orbited closer and closer.)
How to see the Lyrids April meteor shower

CNN —After no major annual meteor showers for months, the Lyrids are here to end the drought. Known as one of the oldest-recorded meteor showers, the Lyrids are expected to produce 10 to 15 meteors per hour for three nights centered around its peak of 9:06 p.m. Lyrids’ history dates back centuriesThe Lyrids were first recorded in 687 BC, according to NASA, making this meteor shower to be one of the oldest recorded. “Only in the 19th century was when we kind of understood that they actually came from space.”Every meteor shower has a parent comet from which comes the debris that makes up the shower. For those in Africa, Asia and Australia, a penumbral lunar eclipse will occur on May 5, and on October 28, a partial lunar eclipse will be viewable in Europe, Asia, Australia, Africa, parts of North America and much of South America.
NASA's Hubble Space Telescope is getting more satellites ruining its images, a new study found. Hubble images streaked with white lines show the impact of just one satellite flying through the telescope's field of view.

NASA space telescopes detected the brightest explosion ever recorded. Images show the faint object erupting with powerful gamma rays. About 1.9 billion years ago, a dying star collapsed, exploding in a powerful burst of gamma rays that careened toward Earth. Images taken in visible light by Swift’s Ultraviolet/Optical Telescope show how the afterglow of GRB 221009A (circled) faded over the course of about 10 hours. It could be decades before another gamma-ray burst this bright appears again.
