This Planet Survived Death Sentence – Nobody Knows How
Stars tend to get violent when they’re about to die. And it is not easy for the planets that orbit them. Take our Sun, for example: in about 5 billion…
First ultraviolet data collected by European Space Agency’s JUICE mission
The SwRI-led Ultraviolet Spectrograph (UVS) aboard ESA’s Jupiter Icy Moons Explorer, JUICE, has successfully completed its initial commissioning following the spacecraft’s April 14 launch. This segment of JUICE-UVS data shows…
An Impossible Planet? The Story of Halla
Here’s a story of how an exoplanet named Halla survived the rebellion of its home star Baekdu. When stars, similar to the sun, have reached the end of their lifetime,…
Astronomers use dead stars to measure gravitational waves produced by ancient black holes
The NANOGrav team used a number of radio telescopes, including the Green Bank Telescope in West Virginia, to listen to pulsars for 15 years. Credit: NRAO/AUI/NSF, CC BY An international…
IceCube: Milky Way Galaxy is Neutrino Desert
The Milky Way galaxy is an awe-inspiring feature of the night sky, dominating all wavelengths of light and viewable with the naked eye as a hazy band of stars stretching…
Sun releases strong solar flare
NASA’s Solar Dynamics Observatory captured this image of a solar flare—as seen in the bright flash on the top right area of the sun—on July 2, 2023. The image shows…
Collaborative research detects nanojets with machine learning algorithms

After 15 Years, Evidence of Cosmic Gravitational Wave Background
The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. Artist’s interpretation of an array of…
Scientists have finally ‘heard’ the chorus of gravitational waves that ripple through the universe
This undated photo provided by researchers in June 2023 shows the Arecibo Telescope in Puerto Rico. This and several other telescopes around the world were used to observe the slow…
