Astrophysics Team Lights the Way for More Accurate Model of the Universe

Oct. 19, 2020 — Scientists demonstrated the first use of a method called self-calibration to remove contamination from gravitational lensing signals. The results should lead to more accurate cosmological models of ...

The Milky Way Galaxy Has a Clumpy Halo

Oct. 19, 2020 — Astronomers at the University of Iowa have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. The ...

Two Planets Around a Red Dwarf

Oct. 16, 2020 — Astronomers have detected two exoplanets orbiting the star TOI-1266. The telescope thus demonstrates its high precision and takes an important step in the quest of finding potentially habitable ...

Anemic Star Cluster Breaks Metal-Poor Record

Oct. 15, 2020 — In a surprising discovery, astronomers have found a star cluster in the Andromeda Galaxy that contains a record-breaking low amount of metals, calling into question the so-called 'metallicity-floor' ...

Star Clusters Are Only the Tip of the Iceberg

Oct. 15, 2020 — Star clusters have been part of the Imaginarium of human civilization for millennia. The brightest star clusters to Earth, like the Pleiades, are readily visible to the naked eye. A team around ...

NASA's James Webb Telescopes Will Reveal Hidden Galaxies

Oct. 15, 2020 — Simulations show it's possible to distinguish host galaxy from quasars, although still challenging due to the galaxy's small size on the ...

The Mountains of Pluto Are Snowcapped, but Not for the Same Reasons as on Earth

Oct. 13, 2020 — In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such ...

The Black Hole Always Chirps Twice: New Clues Deciphering the Shape of Black Holes

Oct. 8, 2020 — Gravitational-wave scientists reveal that when two black holes collide and merge, the remnant black hole 'chirps' not once, but multiple times, ...

Astronomers Solve Dark Matter Puzzle of Strange Galaxy

Oct. 13, 2020 — Astronomers have found that the total number of globular clusters around Dragonfly 44 and, therefore, the dark matter content, is much less than earlier findings had suggested, which shows that this ...

Studying the Sun as a Star to Understand Stellar Flares and Exoplanets

Oct. 12, 2020 — New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also ...

Astronomers Find X-Rays Lingering Years After Landmark Neutron Star Collision

Oct. 12, 2020 — It's been three years since the landmark detection of a neutron star merger from gravitational waves. Since that day, an international team of ...

ESO Telescopes Record Last Moments of Star Devoured by a Black Hole
