Astronomers Could Spot Clues to Alien Life 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 —…

Strange spots scattered across the Moon’s nearside where bedrock is conspicuously exposed are evidence of seismic activity set in motion 4.3 billion years ago that…
Mercury is a desert world which scientists until recently considered quite uninteresting. NASA’s Mariner and MESSENGER missions, however, revealed that there is much more to…
A reasonably small 4-8 m (~13-26 foot) asteroid recently flew by Earth, passing close to satellites orbiting in the geostationary ring at a distance of…
In the forests of the night lies a barred spiral galaxy called NGC 3583, imaged here by the NASA/ESA Hubble Space Telescope. This is a…
Mars had a global magnetic field much earlier—and much later—in the planet’s history than scientists have previously known. A planet’s global magnetic field arises from…
Gravitational-wave astronomy provides a unique new way to study the expansion history of the Universe. On August 17, 2017, the LIGO and Virgo collaborations first…
An analysis of 369 solar-like stars shows that solar brightness variations are extremely weak. The extent to which solar activity (and thus the number of…
The weather forecast for the giant, super-hot, Jupiter-size planet WASP-79b is steamy humidity, scattered clouds, iron rain, and yellow skies. NASA’s Hubble Space Telescope teamed…
Computer models of merging neutron stars predicts new signature in the gravitational waves to tell when this happens. Neutron stars are among the densest objects…
Vaneeza Rupani’s essay was chosen as the name for the small spacecraft, which will mark NASA’s first attempt at powered flight on another planet. Destined…
Hawaii astronomer discovers massive extrasolar planet with Maunakea telescope. Our solar system has a king. The planet Jupiter, named for the most powerful god in…
The comet was first discovered in December 2019 by the ATLAS (Asteroid Terrestrial-impact Last Alert System) robotic astronomical survey system in Hawaiʻi, USA. It brightened…
The recently retired infrared observatory was the only telescope to spot a far-off flash of light that holds clues about the physical characteristics of these…
The large near-Earth object is well known to astronomers and will get no closer than 3.9 million miles to our planet. A large near-Earth asteroid…
A model developed at the Faculty of Physics at the Technion, in collaboration with German scientists at Tübingen, explains the unique properties of Arrokoth –…
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…
A direct, observation-based test of one of the pillars of cosmology. The universe is full of billions of galaxies — but their distribution across space…
