UBC researchers establish new timeline for ancient magnetic field on Mars
Mars had a global magnetic field much earlier--and much later--in the planet's history than scientists have previously known.
New study examines which galaxies are best for intelligent life
Giant elliptical galaxies are not as likely as previously thought to be cradles of technological civilizations such as our own, according to a recent paper by a University of Arkansas astrophysicist.
Astronomers could spot life signs orbiting long-dead stars
The next generation of powerful Earth- and space-based telescopes will be able to hunt distant solar systems for evidence of life on Earth-like exoplanets - particularly those that chaperone burned-out stars known as white dwarfs.
Astronomers capture rare images of planet-forming disks around stars
An international team of astronomers has captured fifteen images of the inner rims of planet-forming disks located hundreds of light years away.
Newly discovered exoplanet dethrones former king of Kepler-88 planetary system
Maunakea, Hawaii - Our solar system has a king. The planet Jupiter, named for the most powerful god in the Greek pantheon, has bossed around the other planets through its gravitational influence.
4-billion-year-old nitrogen-containing organic molecules discovered in Martian meteorites
A research team has found nitrogen-bearing organic material in carbonate minerals in a Martian meteorite.
Hubble watches comet ATLAS disintegrate into more than 2 dozen pieces
These two Hubble Space Telescope images of comet C/2019 Y4 (ATLAS), taken on April 20 and 23, 2020, provide the sharpest views yet of the breakup of the fragile comet.
The weight of the Universe
Bochum cosmologists headed by Professor Hendrik Hildebrandt have gained new insights into the density and structure of matter in the Universe.
‘Elegant’ solution reveals how the universe got its structure
The universe is full of billions of galaxies--but their distribution across space is far from uniform. Why do we see so much structure in the universe today and how did it all form and grow?
Hubble celebrates its 30th anniversary with a tapestry of blazing starbirth
Hubble Space Telescope's iconic images and scientific breakthroughs have redefined our view of the Universe.
An eclipsing binary millisecond pulsar discovered by FAST
Using the data obtained by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. PAN Zhichen and Prof. LI Di from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) discovered an eclipsing binary millisecond pulsar in Globular Cluster (GC) Messier 92 (M92).
Researchers monitor near-Earth asteroid
The Arecibo Observatory in Puerto Rico is following an asteroid approaching Earth this week and while it poses no threat, it appears to know our planet is facing a pandemic.
Promising signs for Perseverance rover in its quest for past Martian life
New research indicates river delta deposits within Mars' Jezero crater - the destination of NASA' Perseverance rover on the Red Planet - formed over time scales that promoted habitability and enhanced preservation of evidence.
Atmospheric tidal waves maintain Venus’ super-rotation
Images from the Akatsuki spacecraft unveil what keeps Venus's atmosphere rotating much faster than the planet itself.
Researchers use ‘hot Jupiter’ data to mine exoplanet chemistry
After spotting a curious pattern in scientific papers - they described exoplanets as being cooler than expected - Cornell University astronomers have improved a mathematical model to accurately gauge the temperatures of planets from solar systems hundreds of light-years away.
