Astronomers Reveal Unified Model for Galactic Discs: Star Formation, Turbulence Driving, and Mass Transport
Disc galaxies like our own Milky Way, characterized by a flattened disc of stars and gas (often with a central bulge of material as well)…

Chandra data indicates that a young star, known as RW Aur A, has likely destroyed and consumed an infant planet. If confirmed, this would be…
In 1610, Galileo redesigned the telescope and discovered Jupiter’s four largest moons. Nearly 400 years later, NASA’s Hubble Space Telescope used its powerful optics to…
These six infrared images of Saturn’s moon Titan represent some of the clearest, most seamless-looking global views of the icy moon’s surface produced so far….
Twelve new moons orbiting Jupiter have been found—11 “normal” outer moons, and one that they’re calling an “oddball.” This brings Jupiter’s total number of known…
ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test…
The “ghostly particle” is confirmed to have originated from a blazar, nearly 4 billion light years from Earth. For the first time, scientists from around…
Launched nearly 15 years ago on August 25, 2003, the Spitzer Space Telescope is the final mission in NASA’s Great Observatories Program — a family…
Pasadena Conference to Include New Insight into Dwarf Planet Ceres As NASA’s Dawn spacecraft prepares to wrap up its groundbreaking 11-year mission, which has included…
The path of light from a star as it passes by a massive body, like an exoplanet, will be bent and an observer looking toward…
The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for…
At first glance, it may seem as though this image was taken through a faulty lens, but the mind-bending distortions visible in this Hubble Wide…
Data collected by NASA’s Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole…
This image from NASA’s Mars Reconnaissance Orbiter, acquired May 13, 2018, during winter at the South Pole of Mars, shows a carbon dioxide ice cap…
Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe’s expansion rate. The results…
New observations by three of the world‘s largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000…
For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This…
Astronomers and physicists around the world, including in Hawaii, have begun to unravel a long-standing cosmic mystery. Using a vast array of telescopes in space…
