Scientists have determined that a rare element found in some of the oldest solids in the solar system, such as meteorites, and previously thought to have been forged in supernova explosions, actually predate such cosmic events, ...
In a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter.
It sounds fantastical, but it's a reality for the scientists who work at the world's largest particle collider.
Using the Gemini Observatory and the Hubble Space Telescope (HST), an international team of astronomers has investigated a Galactic globular cluster known as NGC 6558. Results of the new study, published July 22 on the pre-print ...
The dense peaks in the wavelength distribution graph observed in a Lyman-Alpha forest indeed resemble many small trees. Each of those peaks represents a sudden drop in "light" at a specific and narrow wavelength, effectively ...
This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor.
Today, enormous stretches of space are crystal clear, but that wasn't always the case. During its infancy, the universe was filled with a "fog" that made it opaque, cloaking the first stars and galaxies. NASA's upcoming Nancy ...
The field of extrasolar planet studies has grown exponentially in the past 20 years. Thanks to missions like Kepler, the Transiting Exoplanet Survey Satellite (TESS), and other dedicated observatories, astronomers have confirmed ...
Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter. The two clusters each contain thousands ...
What is dark matter? Even for astrophysicists, it's a question that remains unanswered. These invisible particles make up most of the matter in the universe and about a quarter of the universe as a whole. They are thought ...
