Researchers at the University of Colorado Boulder have completed an unprecedented 'dissection' of twin galaxies in the final stages of merging. The new study, led by CU Boulder research associate Francisco Müller-Sánchez, explores a galaxy called NGC 6240. While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two -- and they're circling each other in the last steps before crashing together.
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons, as detailed in a paper published today in Science Advances.
New research published in The Astrophysical Journal examines an interesting light source that was captured by four different telescopes each pointing in a different direction in the sky.
Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes -- known as filaments -- that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.
An international team of researchers has imaged newly forming jets of plasma from a massive black hole with unprecedented accuracy. Radio images made with a combination of telescopes in space and on the ground resolve the jet structure merely a couple of hundred black hole radii or 12 light days from its launching site.
Peering through the gravitational lens of a massive galaxy cluster 5 billion light years from Earth, astronomers have discovered a single, blue supergiant star 9 billion light years away, farther than any other normal star seen before. The star, dubbed Icarus, was magnified more than 2,000 times when it passed directly behind a sun-like star in the lensing cluster. This demonstrates a new way of studying stars in the earliest years of the universe.
In the search for extraterrestrial life, scientists have turned over all sorts of rocks. Mars, for example, has geological features that suggest it once had -- and still has -- subsurface liquid water. Scientists have also eyed Saturn's moons as well as Jupiter's as possible havens for life in the oceans under their icy crusts. Now, however, scientists are dusting off an old idea that promises a new vista in the hunt for life beyond Earth: the clouds of Venus.
Project Mercury proved that humans could live and work in space, paving the way for all future human exploration.
In 'Making Life Multi-Planetary' Elon Musk, CEO and Lead Designer at SpaceX, presents the updated design for the Big Falcon Rocket, the powerful rocket intended to propel a newly modified space vehicle to the International Space Station and beyond to fulfill his vision for establishing a human presence on Mars.
On the outskirts of our galaxy, a cosmic tug-of-war is unfolding-and only NASA's Hubble Space Telescope can see who's winning.
