University of Bristol astrophysicists are helping shed new light on an Earth-sized exoplanet 40 light years away where liquid water in the form of a global ocean or icy expanse might exist on its surface. That would only be possible if an atmosphere is present—a big mystery that the scientists are attempting to unravel and […]
Stargazers enjoyed a “Blood Moon” Sunday night during a total lunar eclipse visible across Asia and swaths of Europe and Africa.

While it may appear as just another spiral galaxy among billions in the universe, this image from the NASA/ESA Hubble Space Telescope reveals a galaxy with plenty to study. The galaxy, NGC 7456, is located over 51 million light-years away in the constellation Grus (the Crane).

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many of these planets have properties that differ significantly from the eight planets in our solar system. How are such diverse exoplanets formed and evolved, and which of them could potentially become Earth-like planets capable of […]
A research team led by Ph.D. candidate Wang Haozhi under the supervision of Prof. Ali Esamdin at the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) has revealed the genuine source of the pulsating star KOI-1755 transit signal using the Kepler space telescope. Their findings are published in The Astronomical Journal.

Large exoplanets are more easily detected than small ones. It’s axiomatic. While large planets block out more starlight during transits, small planets block out much less, letting them hide in the overpowering glare from their stars. To help detect sub-Jupiter mass exoplanets, astronomers search for the effect these planets can have on their surroundings.

Astronomers and students working together through a unique educational initiative have obtained a striking new image of the growing tail of interstellar Comet 3I/ATLAS. The observations reveal a prominent tail and glowing coma from this rare celestial visitor, while also providing new scientific measurements of its colors and composition.

This week marks 48 years since the Sept. 5, 1977, launch of NASA’s Voyager 1 spacecraft from Cape Canaveral, Florida, to study Jupiter and Saturn up close. Nearly a half-century later, Voyager 1 and its twin, Voyager 2 are still exploring. Only now they’re in the outer reaches of our solar system.

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a proton. By making these extremely precise measurements, LIGO, which consists of two facilities—one in Washington and one in Louisiana—can detect undulations in space-time […]
JetBlue Airways will become the first airline to use Amazon’s Project Kuiper satellite network to power its in-flight Wi‑Fi service, the companies announced Wednesday, as the online retail giant tries to challenge the dominance of Elon Musk’s Starlink.
