Astronomers have performed an extensive study of the properties of galaxies within filaments formed at different times during the age of the universe.
Mars may have been a wetter place than previously thought, according to research on simulated Martian meteorites.
UGC 12591 sits somewhere between a lenticular and a spiral. It lies just under 400 million light-years away from us in the westernmost region of the Pisces-Perseus Supercluster.
With the discovery of seven earth-sized planets around the TRAPPIST-1 star 40 light years away, astronomers are looking to the upcoming James Webb Space Telescope to help us find out if any of these planets could possibly support life.
Scientists have proven that the warning signs of one type of space weather event can be detected up to 17 minutes before it arrives at Earth -- critical time that could help protect astronauts in space.
Two separate investigations determine that microorganisms can survive on the surface of Mars, and deep in its subsurface.
New research represents a significant improvement on previous detection constraints, and a substantial step forward in the search for dark matter.
Scientists have made the most detailed observation yet of a black hole outflow, from the active galaxy IRAS 13224-3809. The outflow's temperature changed on time scales of less than an hour -- hundreds of times faster than ever seen before. The rapid fluctuations in the outflow's temperature also indicated that the outflow was responding to X-ray emissions from the accretion disk, a dense zone of gas and other materials that surrounds the black hole.
There may be a large number of undetected bright, substellar objects similar to giant exoplanets in our own solar neighborhood, according to new work.
One of the highest-resolution maps of dark matter ever created has now been revealed, offering a detailed case for the existence of cold dark matter -- sluggish particles that comprise the bulk of matter in the universe.
The first images from the Solar Ultraviolet Imager or SUVI instrument aboard NOAA's GOES-16 satellite have been successful, capturing a large coronal hole on Jan. 29, 2017.
The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe.
Scientists have published a 'cosmic census' of a large swath of the night sky containing roughly 100 million stars and galaxies, including some of the most distant objects in the universe. These high-quality images allow an unprecedented view into the nature and evolution of galaxies and dark matter.
NASA is developing a new family of flexible heat-shield systems with a woven carbon-fiber base material, and is using X-rays to test the designs.
This colorful stripe of stars, gas, and dust is actually a spiral galaxy named NGC 1055. Captured here by ESO's Very Large Telescope (VLT), this big galaxy is thought to be up to 15 percent larger in diameter than the Milky Way. NGC 1055 appears to lack the whirling arms characteristic of a spiral, as it is seen edge-on. However, it displays odd twists in its structure that were probably caused by an interaction with a large neighboring galaxy.
A trip past the sun may have selectively altered the production of one form of water in a comet -- an effect not seen by astronomers before, a new study suggests.
When the universe was young, a supermassive black hole heaved out a jet of particle-infused energy that raced through space at nearly the speed of light. Billions of years later, scientists has identified this black hole and four others similar to it that range in age from 1.4 billion to 1.9 billion years old.
Hunting for habitable exoplanets now may be easier: astronomers report that hydrogen pouring from volcanic sources on planets throughout the universe could improve the chances of locating life in the cosmos.
Astronomers have found evidence demonstrating that stars are ripped apart by supermassive black holes 100 times more often than previously thought.
Evidence of planetary debris surrounding a double sun, 'Tatooine-like' system has been found for the first time, report investigators.
