When NASA’s OSIRIS-REx spacecraft collected samples from asteroid Bennu’s surface in 2020, forces measured during the interaction provided scientists with a direct test of the poorly understood near-subsurface physical properties of rubble-pile asteroids. Now, a Southwest Research Institute-led study has characterized the layer just below the asteroid’s surface as composed of weakly bound rock fragments containing twice the void space as the overall asteroid.
How often do stars live alone? For brown dwarfs — objects that straddle the boundary between the most massive planets and the smallest stars — astronomers need to uncover more examples of their companions to find out. Ace citizen scientist Frank Kiwy has done just that by using the Astro Data Lab science platform at NSF’s NOIRLab to discover 34 new ultracool dwarf binary systems in the Sun’s neighborhood, nearly doubling the number of such systems known.
As telescopes have become more advanced and powerful, astronomers have been able to detect more and more distant galaxies. These are some of the earliest galaxies to form in our universe that began to recede away from us as the universe expanded.
Liquid water is an important prerequisite for life to develop on a planet. As researchers from the University of Bern, the University of Zurich and the National Centre of Competence in Research (NCCR) PlanetS report in a new study, liquid water could also exist for billions of years on planets that are very different from Earth. This calls our currently Earth-centred idea of potentially habitable planets into question.
Telescopes have spotted many distant galaxies – but none earlier than 400 million years after the big bang. What were galaxies that existed even earlier like? Two research teams using the James Webb Space Telescope will wield its state-of-the-art instruments to reveal an untold number of details about this early period in the universe for the first time – and revise what we know about some of the earliest chapters of galaxy evolution.
A star’s death throes have so violently disrupted its planetary system that the dead star left behind, called a white dwarf, is siphoning off debris from both the system’s inner and outer reaches. This is the first time astronomers have observed a white dwarf star that is consuming both rocky-metallic and icy material, the ingredients of planets.
University of Kentucky postdoc presents important new findings about black holes and their host galaxies at American Astronomical Society meeting
If, as astronomers believe, the death of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black holes are invisible.
With a new simulation that shows how satellite galaxies orbit bigger galaxies like the Milky Way, Johns Hopkins University researchers have reconciled long-dueling visions of what astronomers actually see using telescopes and what theorists have predicted they should see.
Seven new scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA), the Very Large Array (VLA), and the Very Large Array Sky Survey (VLASS) will be revealed at multiple press conferences during the 240th meeting of the American Astronomical Society (AAS) between June 13-15, 2022 in Pasadena, California.
Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University astronomers have found a way to determine the relative age of hot Jupiters using new measurements from the Gaia spacecraft, which is tracking over a billion stars.
A recently discovered, rare and persistent rapid-fire fast radio burst source – sending out an occasional and informative cosmic ping from more than 3.5 billion light years away – helps to reveal the secrets of the broiling hot space between the galaxies. That’s according to an international team of astronomers who published their findings in the journal Nature.
A thorough understanding of galaxy evolution depends in part on an accurate measurement of the abundance of metals in the intergalactic medium – the space between stars – but dust can impede observations in optical wavelengths.
Nearly half of Sun-size stars are binary. According to University of Copenhagen research, planetary systems around binary stars may be very different from those around single stars. This points to new targets in the search for extraterrestrial life forms.
