As Chile and Argentina witnessed the total solar eclipse on December 14, 2020, unbeknownst to skywatchers, a little tiny speck was flying past the Sun…
Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and…
A unique stage of planetary system evolution has been imaged by astronomers, showing fast-moving carbon monoxide gas flowing away from a star system over 400…
An international study led by the University of Turku discovered phosphorus and fluorine in solid dust particles collected from a comet. The finding indicates that…
ESA’s Rosetta mission discovers unique aurora at Comet 67P/Churyumov-Gerasimenko. Data from Southwest Research Institute-led instruments aboard ESA’s Rosetta spacecraft have helped reveal auroral emissions in…
A study of comet motions indicates that the Solar System has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that…
First-ever measurements provide evidence that extremely cold liquid water exists in two distinct structures that co-exist and vary in proportion dependent on temperature. Supercooled water…
An atmospheric light show previously relegated to planets and Jupiter moons is found on comet using data from ESA’s Rosetta spacecraft. Data from NASA instruments…
In the aurora borealis on Earth, electrically charged particles of the solar wind move along the Earth’s magnetic field. At high latitudes, these strike nitrogen…
A permeable heart with a hardened facade — the resting place of Rosetta’s lander on Comet 67P/Churyumov-Gerasimenko is revealing more about the interior of the…
NASA Hubble Space Telescope images of comet NEOWISE, taken on August 8, zero in on the visitor’s coma, the gossamer shell of gas and dust…
Discovered in March 2020, Comet NEOWISE became visible to the naked eye in July, gifting observers in the northern hemisphere with one of the most…
Faintly in the distance, Comet C/2020 F3 NEOWISE (Comet NEOWISE) streaked across the sky above the tree line of Lone Pine Lake, located on the…
The International Space Station, with a crew of five onboard, is seen in this 10 second exposure above comet NEOWISE, Saturday, July 18, 2020 from…
Look up toward the stars this month, and you just might spot the brightest comet to grace Northern Hemisphere skies in decades. In July 2020,…
Skygazers across the Northern Hemisphere are being treated to stunning views of comet NEOWISE as it streaks past Earth. Amateur astrophotographer Javier Manteca got a…
Observers in the Northern Hemisphere are hoping to catch a glimpse of Comet NEOWISE as it zips through the inner solar system before it speeds…
