The black hole at the centre of our galaxy, Sagittarius A*, has been visualised in virtual reality for the first time. The details are described in an article published in the open access journal Computational Astrophysics and Cosmology.
Caught in the act of landfall, Tropical Cyclone Gaja was seen by NASA's Aqua satellite as it passed overhead and collected temperature information.
A year ago, astronomers identified the first interstellar visitor to our solar system. 'Oumuamua was studied by nearly every telescope available, including the ultra-sensitive Spitzer infrared space telescope. Despite a whopping 33 hours of observation time, 'Oumuamua proved too faint for Spitzer to see. Nevertheless, this allowed the observation team to draw significant conclusions. Their analysis of the visitor was published online on Nov. 14 by The Astronomical Journal.
Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research led by The University of Texas at Austin has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks.
Analyzing data from NASA's Magnetospheric Multiscale (MMS) mission, a team led by Southwest Research Institute (SwRI) has found that the small regions in the Earth's magnetosphere that energize the polar aurora are remarkably calm and nonturbulent.
NASA's Magnetospheric Multiscale mission has been observing a type of space explosion called magnetic reconnection for three years. MMS just witnessed such an explosion in a unique location: the part of Earth's magnetic environment trailing behind the planet, away from the Sun -- with enough resolution to reveal its true nature more clearly.
ALMA data show the most luminous galaxy in the universe has been caught in the act of stripping away nearly half the mass from at least three of its smaller neighbors.
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving 'magnetic reconnection' -- the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion -- in the Earth's magnetotail, the magnetic environment that trails behind the planet.
It's not every day you get to observe a gamma-ray binary system. In fact, it's a once-in-a-lifetime experience comparable to seeing Halley's Comet or a solar eclipse. Here's what a UD team saw.
Astronomers may have finally uncovered the long-sought progenitor to a specific type of exploding star by sifting through NASA Hubble Space Telescope archival data. The supernova, called a Type Ic, is thought to detonate after its massive star has shed or been stripped of its outer layers of hydrogen and helium.
