At a time when there were few other Black astrophysicists, he developed a telescopic device that went to the moon on Apollo 16.

Kraken Mare, a sea of liquid methane on Saturn's moon Titan, is at least 100-m (330 feet) deep near its center, according to an analysis of data collected by the RADAR altimeter onboard NASA's Cassini spacecraft on August 21, 2014.

Far below the gaseous atmospheric shroud on Saturn's largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Astronomers have estimated that sea to be at least 1,000-feet deep near its center - enough room for a potential robotic submarine to explore.

MIT researcher Mark Vogelsberger received a share of the 2020 Buchalter Cosmology Prize for simulating galaxy formation in the early universe with ultralight or "fuzzy" dark matter.

We missen juist te vaak leiders die hun nek uitsteken en eindelijk eens niet politiek correct zijn.

MIT PhD candidate Lucio Milanese offers a newly discovered mechanism called "dynamic phase alignment" to uncover how turbulence transfers energy from large scales to smaller scales.

Astronomers may be getting closer to discovering as-yet hidden cosmic secrets, such as the nature of dark matter and the presence of widespread distortions in space-time, researchers reported at the 237th American Astronomical Society meeting, held virtually this week.

Stellar Astrophysics White dwarfs are dense stellar remnants left when a dying parent star throws off its outer layers. The high gravitational fields should cause heavy elements to rapidly sink below the white dwarf surface. Nevertheless some "polluted" white dwarfs have evidence for those materials on their surface, which is thought to be due to the recent accretion of rocky bodies from a surrounding planetary…

Researchers at NASA and in Japan have found HMT — a key ingredient for life — trapped inside an asteroid. This chemical is used in building other organic materials, including some ...

Observations of distant galaxies have seen signs of a modified theory of gravity that could dispense with the invisible, intangible and all-pervasive dark matter.

Despite similarities, "We don't think the universe was created by a giant slime mold."

In a new paper published in the journal Physical Review D, physicists from the United States and Germany argue that if gravitational waves hit a supermassive black hole or a cluster of galaxies on their way to Earth, their signature would change.

Earth sits outside the region of the Milky Way where life is most likely to have arisen, say astronomers.

Astronomers are studying black holes that could have formed in the early universe, before stars and galaxies were born. Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed supermassive black holes found in the center of our Galaxy and other galaxies.

Today's video games offer an incredibly realistic, immersive experience, due in large part to their true-to-life simulations of physical phenomena. By far the most commonly simulated effects are those of Rigid Body Dynamics. Toptal is pleased to have our very own Nilson Souto present this first installment of our...
