New Image from James Webb Space Telescope Reveals Astonishing Saturn and Its Rings

Saturn's iconic rings seem to glow eerily in this incredible infrared picture, which also unveils unexpected features in Saturn's atmosphere. This image serves as context for an observing program that will test the telescope's capacity to detect ...

Gravitational Waves from Colossal Black Holes Found Using 'Cosmic Clocks'

You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy. New results are the first evidence of the gravitational wave background -- a sort of soup ...

Life After Death: Astronomers Find a Planet That Shouldn't Exist

明星会膨胀到p的1.5倍lanet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...

Starlight and the First Black Holes: Researchers Detect the Host Galaxies of Quasars in the Early Universe

For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big ...

Astronomers Discover Last Three Planets Kepler Telescope Observed Before Going Dark

With the help of citizen scientists, astronomers discovered what may be the last three planets that the Kepler Space Telescope saw before it was ...

One-Third of Galaxy's Most Common Planets Could Be in Habitable Zone

A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid ...

X-Ray Emissions from Black Hole Jets Vary Unexpectedly, Challenging Leading Model of Particle Acceleration

Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door ...


Astronomers Discover a Key Planetary System to Understand the Formation Mechanism of the Mysterious 'Super-Earths'

A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. ...

Helium Nuclei Research Advances Our Understanding of Cosmic Ray Origin and Propagation

The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray ...

Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the ...

An X-Ray Look at the Heart of Powerful Quasars

Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective ...

Radio Signal Reveals Supernova Origin

Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf ...

NASA's Spitzer, TESS Find Potentially Volcano-Covered Earth-Size World
