By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of…
Galaxy Cluster’s Gravity Produces Mirror Images of Distant Galaxy Behind It Gazing into the universe is like looking into a funhouse mirror. That’s because gravity…
Using the H.E.S.S. observatory, researchers at GRB 190829A observe unusual features that challenge models. Researchers from the H.E.S.S. Collaboration succeeded to derive the intrinsic spectrum…
What’s Up for October? What to look for this month at sunrise and sunset, and two brilliant stars vying for the “pole” position. On October…
This Picture of the Week features two interacting galaxies that are so intertwined, they have a collective name — Arp 91. This delicate galactic dance…
NASA’s Nancy Grace Roman Space Telescope has successfully passed its critical design review, signaling that all design and developmental engineering work is now complete. “After…
New study reveals that early galaxies have no fuel, and something is stopping them from refilling the tank. Early massive galaxies—those that formed in the…
Galaxies exchange matter with their external environment thanks to galactic winds. The MUSE instrument from the Very Large Telescope has, for the very first time,…
Potential discovery of a circumtriple planet has implications for bolstering our understanding of planet formation. In a distant star system — a mere 1,300 light…
Most stars including the Sun generate magnetic activity that drives a fast-moving, ionized wind and also produces X-ray and ultraviolet emission (often referred to as…
Researchers can now hold stellar nurseries in their hands thanks to 3D printing, revealing features often obscured in traditional renderings and animations. Astronomers can’t touch…
In the 2030’s, gravitational-wave detectors will be thousands of times more sensitive than Advanced LIGO, Virgo, and KAGRA. The network of “third generation” (3G) observatories…
Short gamma-ray bursts are extremely bright bursts of high-energy light that last for a couple of seconds. In many of these bursts, there is a…
Every day for over two decades, the U.S. has had a presence at Mars, using spacecraft to understand this extreme world and its potential as…
Researchers will observe more than a dozen protoplanetary systems to gather data about their inner disks – where Earth-like planets may be forming What was…
Unprecedent measurements confirm galaxies idle when they run out of cold gas. New research, published in Nature and led by the University of Massachusetts Amherst, has just answered…
Meet NGC 5728, a spiral galaxy around 130 million light-years from Earth. This image was captured using Hubble’s Wide Field Camera 3 (WFC3), which is…
Since 2020, a “sonification” project has transformed astronomical data from some of the world’s most powerful telescopes into sound. Three new objects — a star-forming…
