A team of astronomers led by Anne-Marie Lagrange, a CNRS researcher, has discovered a second giant planet in orbit around β Pictoris, a star that is relatively young (23 million years old) and close (63.4 light years), and surrounded by a disk of dust. The β Pictoris system has fascinated astronomers for the last 30 years since it enables them to observe a planetary system in the process of forming around its star.
University of Arizona researchers are using the Catalina Sky Survey's near-Earth object telescopes to locate the optical counterparts to gravitational waves triggered by massive mergers.
If our eyes could see gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade.
A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun.
New research from astronomers at the University of Washington uses the intriguing TRAPPIST-1 planetary system as a kind of laboratory to model not the planets themselves, but how the coming James Webb Space Telescope might detect and study their atmospheres, on the path toward looking for life beyond Earth.
Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell University research.
Recent research shows that our planet may have been pummeled with asteroids long before some scientists had previously thought.
The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter's clouds in this new image taken on June 27, 2019. It features the planet's trademark Great Red Spot and a more intense colour palette in the clouds swirling in the planet's turbulent atmosphere than seen in previous years.
This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter's atmosphere.
Astronomers are planning to hunt for cores of exoplanets around white dwarf stars by 'tuning in' to the radio waves that they emit.
