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…

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…
Gravitational waves, first detected in 2016, offer a new window into the universe, with the potential to tell us about everything from the time following…
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…
How do you observe a process that takes more than one trillion times longer than the age of the universe? The XENON Collaboration research team…
Most everybody is familiar with the Big Bang — the notion that an impossibly hot, dense universe exploded into the one we know today. But…
The first type of molecule that ever formed in the universe has been detected in space for the first time, after decades of searching. Scientists…
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of…
Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts–one of the…
Astronomers used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to make the first direct image of a dusty, doughnut-shaped feature surrounding…
A Yale-led team of researchers is doubling down on its earlier finding of a galaxy with almost no dark matter. In 2018, the researchers published…
Researchers from Russia, Finland, and the U.S. have put a constraint on the theoretical model of dark matter particles by analyzing data from astronomical observations…
A team of scientists has proposed a powerful new test for inflation, the theory that the universe dramatically expanded in size in a fleeting fraction…
The center of our galaxy is a frenzy of activity. A behemoth black hole — 4 million times as massive as the sun — blasts…
All massive galaxies are believed to host supermassive black holes (SMBH) at their centers that grow by accreting mass from their environment. The current picture…
Astronomers from Japan, Taiwan, and Princeton University have discovered 83 quasars powered by supermassive black holes in the distant universe, from a time when the…
Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the…
Astronomers have discovered a binary star system with the closest high-mass young stellar objects ever measured, providing a valuable “laboratory” to test theories on high-mass…
