Webb Space Telescope’s Infrared Universe: A New Window to the Cosmos
The James Webb Space Telescope (Webb) will observe the Universe in the near-infrared and mid-infrared – at wavelengths longer than visible light. By viewing the…

Using data from ESA’s Gaia mission, astronomers have shown that a part of the Milky Way known as the ‘thick disc’ began forming 13 billion…
What Are Gravitational Waves? Gravitational waves are distortions in spacetime that result from the movements of objects with mass. Gravitational waves are not simple conceptually,…
A city-sized collapsed star has generated a beam of matter and antimatter that stretches for trillions of miles. Data from NASA’s Chandra X-ray Observatory revealed…
The SPHEREx mission will have some similarities with the James Webb Space Telescope. But the two observatories will take dramatically different approaches to studying the…
Study adds more certainty to theory involving information paradox. Black holes really are giant fuzzballs, a new study says. The study attempts to put to…
Fragments of the interior of a proton have been shown by scientists from Mexico and Poland to exhibit maximum quantum entanglement. The discovery, already confronted…
Named after a goddess of the dawn, the Thesan simulation of the first billion years helps explain how radiation shaped the early universe. It all…
NASA’s Imaging X-ray Polarimetry Explorer (IXPE) mission, a joint effort with the Italian Space Agency, has returned data that no other spacecraft has obtained before…
We’ve all seen the gorgeous images and videos of coronal loops. They’re curved magnetic forms that force brightly glowing plasma to travel along their path….
New study by international team of scientists identifies polarization as key trait that may reveal the origin of the powerful millisecond-long cosmic radio explosions. Nearly…
What Is Gravitational Lensing? Gravitational lensing occurs when a massive celestial body — such as a galaxy cluster — causes a sufficient curvature of spacetime…
The excitement of making discoveries on the global stage is “so much bigger than the pressure,” says Yen-Jie Lee, particle physicist. When Yen-Jie Lee came…
NASA’s Chandra X-ray Observatory continues to study GW170817, a neutron star merger that produced gravitational waves. Many telescopes saw different kinds of light after the…
Major smashups between rocky bodies shaped our solar system. Observations of a similar crash give clues about how frequent these events are around other stars….
By amassing in high-density regions, dust grains avoid drifting toward the star they are orbiting. A key step in the formation of new planets may…
Astronomers have imaged a beam of matter and antimatter that is 40 trillion miles long with NASA’s Chandra X-ray Observatory. The record-breaking beam is powered…
What Is an Atmosphere? An atmosphere is a layer (or several layers) of gas that surrounds a planet, or other celestial body. If a celestial…
