Photos by Brett Tingley, courtesy of the Glamping CollectiveA similar chunk of Dragon trunk was found in Franklin, North Carolina in June. It's when space debris free-falls toward Earth with no one controlling its course. Even though this space debris is relatively small compared to, say, car-sized satellites, it's not harmless.

☆ Astronomers say we may live at the center of a cosmic void 2 billion light-years wide that defies the laws of cosmology

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.

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.

☆ Most distant black hole discovered by Chandra, Webb telescopes
▼ + stars: | 2023-11-07 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

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.

Black holes have been spotted spitting up remnants of stars years after gobbling them up. AdvertisementAdvertisementSince then, the collaborators have been turning their instruments to monitor 24 black holes for years on end. 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.

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.

☆ With a gulp and burp, a bloated star swallows a Jupiter-sized planet

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 spot a sneak peek of Earth's death — a star swallowing a planet whole — for the first time
▼ + stars: | 2023-05-03 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +7 min

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.)

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.

O parte din racheta care a dus săptămâna trecută pe orbită modulul primei stații spațiale chinezești a scăpat de sub control. Experţii estimează că aceasta va intra necontrolat în atmosfera Pământului în jurul datei de 10 mai, iar unele bucăți riscă să cadă și în regiuni locuite. Componenta care a fost scăpată de sub control are 30 de metri lungime și avea la momentul lansării în jur de 21 tone. Cercetătorii susţin că aceasta se deplasează cu aproximativ 27 000 km/h în jurul planetei, astfel că realizează o rotație completă în jurul Pământului în 90 de minute. Totuși, într-un final aceasta va fi atrasă de planetă și va intra în atmosferă, însă specialiştii nu pot estima când se va întâmpla asta decât cu câteva ore înainte.
