The Extended Baryon Oscillation Spectroscopic Survey (eBOSS), the world’s largest galaxy survey, is part of Phase IV of the Sloan Digital Sky Survey (SDSS), a major multi-spectral imaging and spectroscopic redshift survey. Powered by WPeMaticoRead More →
China Has a Plan to Clean Up Space Junk with Lasers Orbital debris (aka. space junk) is one of the greatest problems facing space agencies today. After sixty years of sending rockets, boosters and satellites into space, the situation in the Low Earth Orbit (LEO) has become rather crowded. Given how fast debris in orbit can travel, even the tiniest bits of junk can pose a major threat to the International Space Station and threaten still-active satellites. It’s little wonder then why ever major space agency on the planet is committed to monitoring orbital debris and creating countermeasures for it. So far, proposals have rangedRead More →
Lava Tube Openings Found Near the Moon’s North Pole Between NASA, the Chinese National Space Agency, the European Space Agency and Roscosmos, there’s no shortage of plans for returning to the Moon and creating a permanent base there. Naturally, these plans have given rise to questions of where such bases should be built. So far, the top contenders have been lava tubes that have been spotted in various locations across the surface of the Moon and in the polar regions. Whereas the polar regions are permanently shaded and appear to have abundant ice water, stable lava tubes would offer protection against the elements and harmfulRead More →
In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns—so it’s little wonder that it has earned the nickname of “El Gordo” (“the Fat One” in Spanish)! Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant Universe. Powered by WPeMaticoRead More →
Astronomers have performed abundance measurements for 11 globular clusters in the galaxies NGC 147, NGC 6822, and Messier 33. The new study, presented January 9 in a paper published on arXiv.org, could improve our knowledge about chemical composition of stellar populations in the universe. Powered by WPeMaticoRead More →

Huge Sheets of Ice Found Hidden Just Beneath the Surface of Mars Its an established fact that Mars was once a warmer and wetter place, with liquid water covering much of its surface. But between 4.2 and 3.7 billion years ago, the planet lost its atmosphere, which caused most of its surface water to disappear. Today, much of that water remains hidden beneath the surface in the form of water ice, which is largely restricted to the polar regions. In recent years, scientists have also learned of ice deposits that exist in the equatorial regions of Mars, though it was unlcear how deep they ran.Read More →
To have a full picture of the lives of massive stars, researchers need to study them in all stages – from when they’re a mass of unformed gas and dust, to their often dynamic end-of-life explosions. Powered by WPeMaticoRead More →
Astronomers Figure Out How Black Holes Can Blast Out Relativistic Jets of Material Across Light Years of Space Black holes have been an endless source of fascination ever since Einstein’s Theory of General Relativity predicted their existence. In the past 100 years, the study of black holes has advanced considerably, but the awe and mystery of these objects remains. For instance, scientists have noted that in some cases, black holes have massive jets of charged particles emanating from them that extend for millions of light years. These relativistic jets” – so-named because they propel charged particles at a fraction of the speed of light –Read More →
China Says it Still has Control Over Tiangong-1 and Can Decide Where It’ll Crash The Tiangong-1 space station has been the subject of a lot of interest lately. Though its mission was meant to end in 2013, the China National Space Agency extended its service until 2016. In September of 2017, after much speculation from the international community, the Agency acknowledged that the station’s orbit was degrading and that it would fall to Earth later in the year. Based on updates from satellite trackers, it has been indicated that Tianglong-1 will likely reenter our atmosphere in March of 2018, with the possibility of debris making itRead More →
An international team of scientists led by researchers from the Argelander Institute for Astronomy has mapped the mass distribution in a distant galaxy cluster (RCS2J2327). This cosmic colossus is located in the constellation Pisces at a distance of approximately 6.4 billion light years. According to current research results it consists of about 85 percent invisible dark matter. Powered by WPeMaticoRead More →

Carnival of Space #543 This week’s Carnival of Space is hosted by Gadi Eidelheit at his The Venus Transit blog. Click here to read Carnival of Space #543. And if you’re interested in looking back, here’s an archive to all the past Carnivals of Space. If you’ve got a space-related blog, you should really join the carnival. Just email an entry to susie@schcrew.space, and the next host will link to it. It will help get awareness out there about your writing, help you meet others in the space community – and community is what blogging is all about. And if you really want to helpRead More →
