Unraveling formation time-scales of galactic bulges
Apr 14, 2020 (SPX)
It took several years and a lot of computational power to analyze approximately half a million spectra from a sample that covers all morphological types of non-...
First time methane ice formed on Earth under relevant space conditions
Apr 14, 2020 (SPX)
Methane, known to us as main compound of natural gas, is one of the simplest hydrocarbons. It consists of a carbon atom with four hydrogen atoms: CH4. On Earth,...
Wind speed on a brown dwarf measured for first time
Apr 10, 2020 (JPL)
Described in a paper in the journal Science, the work combines observations by a group of radio telescopes with data from NASA's recently retired infrared obser...
New technique measures wind speed outside the solar system
Apr 10, 2020 (SPX)

Looking for dark matter
Apr 10, 2020 (SPX)
When the earth passes through such a clump, the fundamental properties of matter are altered in ways that can be detected if instruments are sensitive enough. P...
Astronomers measure wind speed on a brown dwarf
Apr 10, 2020 (SPX)
Based on facts known about the giant planets Jupiter and Saturn in our own Solar System, a team of scientists led by Katelyn Allers of Bucknell University reali...
Astronomers stumble upon unexpected features in a distant galaxy using MeerKAT data
Apr 09, 2020 (SPX)
Launched in 2018, the South African MeerKAT radio telescope is a precursor to the Square Kilometre Array (SKA), which aims to answer fundamental astrophysical q...
Researchers discover new information on interstellar magnetic field in solar neighborhood
Apr 09, 2020 (SPX)
Magnetic field has an important role in the processes of stellar and planetary system formation. The study led by Docent Vilppu Piirola and Docent Andrei Berdyu...
Something is lurking in the heart of Quasar 3C 279
Apr 08, 2020 (SPX)
The EHT collaboration continues extracting information from the groundbreaking data collected in its global campaign in April 2017. One target of the observatio...
First-ever photo proof of powerful jet emerging from colliding galaxies
Apr 08, 2020 (SPX)
Furthermore, scientists had previously discovered that these jets could be found in elliptical-shaped galaxies, which can be formed in the merging of two spiral...
Are gamma-ray bursts powered by a star's collapsing magnetic fields?
Apr 08, 2020 (SPX)
Material does not simply catapult from an exploding star, it accelerates to ultra-high speeds along the narrow beam of the gamma-ray jet, leaving astrophysics p...
The Milky Way's satellites help reveal link between dark matter halos and galaxy formation
Apr 07, 2020 (SPX)
Astrophysicists believe that dark matter is responsible for much of that structure, and now researchers at the Department of Energy's SLAC National Accelerator ...
Celebrating 30 years of Hubble
Apr 02, 2020 (SPX)
In addition to providing researchers with more than a million observations and corresponding data, Hubble has provided beautiful and astounding images to the ge...
High altitude water Cherenkov Observatory tests speed of light
Apr 01, 2020 (SPX)
"How relativity behaves at very high energies has real consequences for the world around us," said Pat Harding, an astrophysicist in the Neutron Science and Tec...
NASA's James Webb Space Telescope Full Mirror Deployment a Success
Apr 01, 2020 (SPX)
As Webb progresses towards liftoff in 2021, technicians and engineers have been diligently checking off a long list of final tests the observatory will undergo ...
A funnel of light
Apr 01, 2020 (SPX)
"Developing a theory for a new physical phenomenon which then inspires new experiments seeking after this effect is one of the biggest moments in a theoretical ...
Electron-Eating Neon Causes Star to Collapse
Mar 31, 2020 (SPX)
The researchers were interested in studying the final fate of stars within a mass range of 8 to 10 solar masses, or 8 to 10 times the mass of our Sun. This mass...
New technique looks for dark matter traces in dark places
Mar 27, 2020 (SPX)
But we know little else about dark matter, including whether it is made up of as-yet-undiscovered particles. There are many competing theories for the compositi...
