Einstein’s General Relativity Theory Beginning to Fray at the Edges
More than 100 years after Albert Einstein published his iconic general theory of relativity, it is beginning to fray at the edges, said Andrea Ghez,…
Astronomers Reveal New Measurement for Universe Expansion
Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised…
ALMA Reveals Moon-Forming Disk Around Distant Planet
Using Earth’s most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one…
Chameleon Theory Could Change How Scientists Think About Gravity
Einstein’s theory of General Relativity is world famous – but it might not be the only way to explain how gravity works and how galaxies…
Astronomers Discover Supermassive Black Holes on a Collision Course
Astronomers have spotted a distant pair of titanic black holes headed for a collision. Each black hole’s mass is more than 800 million times that…
Chandra Views Spinning Black Holes Across Cosmic Sea
A new study has revealed how fast some distant, rapidly growing supermassive black holes are spinning. The material around of one these black holes is…
Compounds Discovered in Meteorites May Hold Clues to the Origin of Life
Cyanide and carbon monoxide are both deadly poisons to humans, but compounds containing iron, cyanide, and carbon monoxide discovered in carbon-rich meteorites by a team…
First Detection of Polarized Radio Waves in Gamma Ray Burst Jets
Good fortune and cutting-edge scientific equipment have allowed scientists to observe a Gamma Ray Burst jet with a radio telescope and detect the polarisation of…
Astronomers Discover Cool Halo Gas Spinning Like Galactic Disks
A group of astronomers led by Crystal Martin and Stephanie Ho of the University of California, Santa Barbara, has discovered a dizzying cosmic choreography among…
New Class of ‘Cold Quasars’ Was Unknown Until Now
Astronomers have discovered a new class of “cold quasars” that could change our perception of how galaxies mature. The discovery was announced June 12 at…
Simulations Reveal How Acids Behave in Ultracold Interstellar Space
Solvated acids tend to release a proton. However, they display more complex behaviour under space conditions. Bochum-based researchers from the Cluster of Excellence Ruhr Explores…
Scientists Solve the Mystery of the Galaxy with No Dark Matter
A group of researchers from the Instituto de Astrofísica de Canarias (IAC) has clarified one of the mysteries of 2018 in the field of extragalactic…
Unique Experiments Will Study Cosmic Clashes and Their Mysterious Aftermath
What happens when two supermassive black holes collide? Combining the observing power of two future ESA missions, Athena and LISA, would allow us to study…
Chandra Discovers New Signal for Neutron Star Collision
A neutron star merger without an observed gamma-ray burst has been discovered using NASA’s Chandra X-ray Observatory. This result gives astronomers another way to track…
Scientists Reveal Massive Collision in the Milky Way’s Past
Our Milky Way galaxy has probably collided or otherwise interacted with other galaxies during its lifetime; such interactions are common cosmic occurrences. Astronomers can deduce…
Scientists Show Gravitational Waves Leave Detectable Mark
Gravitational waves, first detected in 2016, offer a new window on the universe, with the potential to tell us about everything from the time following…
Evidence of How a Dwarf Galaxy Contributes to Growth of the Milky Way
Small stellar systems like dwarf galaxies are suggested to be the main building blocks of our Galaxy. However, it is unclear how many and what…
