Breaking the limits: Discovery of the highest-energy photons from a gamma-ray burst Gamma-ray bursts (GRBs) are brief and extremely powerful cosmic explosions, suddenly appearing in the sky, about once per day. They are thought to result from the collapse of massive stars or the merging of neutron stars in distant galaxies. They commence with an initial, very bright flash, called the prompt emission, with a duration ranging from a fraction of a second to hundreds of seconds. The prompt emission is accompanied by the so-called afterglow, a less brighter but longer-lasting emission over a broad range of wavelengths that fades with time. The first GRBRead More →

Conjunction Alert: Jupiter Meets Venus at Dusk Get ready: The queries are inbound. “Did you see those two bright things in the sky last night?” Says a well meaning family member/friend/coworker/random person on Twitter that knows you’re into astronomy. “They were HUGE!” The post Conjunction Alert: Jupiter Meets Venus at Dusk appeared first on Universe Today.

Astronomers investigate stellar content of the open cluster NGC 330 Using the Multi-Unit Spectroscopic Explorer (MUSE) at the Very Large Telescope (VLT) in Chile, astronomers have conducted a spectroscopic study of the young open cluster NGC 330. Results of the research, published on arXiv.org, provide more details about the cluster’s stellar content. phys.org Go to SourceRead More →

Outback telescope captures Milky Way center, discovers remnants of dead stars A radio telescope in the Western Australian outback has captured a spectacular new view of the center of the Milky Way galaxy. The image from the Murchison Widefield Array (MWA) telescope shows what our galaxy would look like if human eyes could see radio waves. phys.org Go to SourceRead More →

Water Vapor Was Just Found on Europa, More Evidence There’s Liquid Water Beneath All that Ice What’s been long-suspected has now been confirmed: Jupiter’s moon Europa has water. As we’ve learned more about the outer Solar System in recent years, Europa has become a high-priority target in the search for life. With this discovery, NASA has just painted a big red bulls-eye on Jupiter’s smallest Galilean moon. “While scientists have not … Continue reading “Water Vapor Was Just Found on Europa, More Evidence There’s Liquid Water Beneath All that Ice” The post Water Vapor Was Just Found on Europa, More Evidence There’s Liquid Water BeneathRead More →

If Astronauts Hibernated on Long Journeys, They’d Need Smaller Spacecraft There’s a disturbing lack of hibernation in our space-faring plans. In movies and books, astronauts pop in and out of hibernation—or stasis, or cryogenic sleep, or suspended animation, or something like it—on a regular basis. If we ever figure out some kind of hibernation, can we take advantage of it to get by with smaller … Continue reading “If Astronauts Hibernated on Long Journeys, They’d Need Smaller Spacecraft” The post If Astronauts Hibernated on Long Journeys, They’d Need Smaller Spacecraft appeared first on Universe Today.

NASA scientists confirm water vapor on Europa Forty years ago, a Voyager spacecraft snapped the first closeup images of Europa, one of Jupiter’s 79 moons. These revealed brownish cracks slicing the moon’s icy surface, which give Europa the look of a veiny eyeball. Missions to the outer solar system in the decades since have amassed enough additional information about Europa to make it a high-priority target of investigation in NASA’s search for life. phys.org Go to SourceRead More →

Scientists Construct a Global Map of Titan’s Geology Titan’s methane-based hydrologic cycle makes it one of the Solar System’s most geologically diverse bodies. There are lakes of methane, methane rainfall, and even “snow” made of complex organic molecules. But all of that detail is hidden under the moon’s dense, hazy atmosphere. Now a team of scientists have used data from the Cassini mission … Continue reading “Scientists Construct a Global Map of Titan’s Geology” The post Scientists Construct a Global Map of Titan’s Geology appeared first on Universe Today.

The measurements of the expansion of the universe don’t add up Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to update the cosmological model. “It’s like trying to thread a cosmic needle,” explains researcher Licia Verde of the University of Barcelona, co-author of an article on the implications of this problem. phys.org Go to SourceRead More →
