The first-ever comet from beyond our Solar System has been successfully imaged by the Gemini Observatory in multiple colors. The image of the newly discovered…
Where did the Earth’s water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water…
As the brilliant comet 46P/Wirtanen streaked across the sky, NASA telescopes caught it on camera from multiple angles. NASA’s Hubble Space Telescope photographed comet 46P/Wirtanen…
On Sunday, December 16, the comet known as 46P/Wirtanen will make one of the 10 closest comet flybys of Earth in 70 years, and you…
The entire history of human existence is a tiny blip in our solar system’s 4.5-billion-year history. No one was around to see planets forming and…
Before NASA’s Transiting Exoplanet Survey Satellite (TESS) started science operations on July 25, 2018, the planet hunter sent back a stunning sequence of serendipitous images…
Scientists have found that molecular oxygen around comet 67P is not produced on its surface, as some suggested, but maybe from its body. The European…
About 70,000 years ago, when the human species was already on Earth, a small reddish star approached our solar system and gravitationally disturbed comets and…
Comets made up of two lobes, such as 67P/Churyumov–Gerasimenko, visited by the Rosetta spacecraft, are produced when the debris resulting from a destructive collision between…
Observations by NASA’s Swift spacecraft, now renamed the Neil Gehrels Swift Observatory after the mission’s late principal investigator, have captured an unprecedented change in the…
The dust that comet 67P/Churyumov-Gerasimenko emits into space consists of about one-half of organic molecules. The dust also belongs to the most pristine and carbon-rich…
NASA’s Infrared Telescope Facility, or IRTF, gave comet 45P a thorough astronomical checkup as it zipped past Earth early in 2017. The results help fill…
The European Space Agency and NASA mission SOHO — short for Solar and Heliospheric Observatory — got a visit from an old friend this week…
Five instruments from the Rosetta Spacecraft reveal the eruption of jets of dust on 67P/Chruyumov-Gerasimenko. The impressive jets of dust that comets emit into space…
Astronomers reveal that a small, recently discovered asteroid — or perhaps a comet — has entered our solar system from somewhere else in our galaxy….
Researchers, working closely with amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star…
New research sheds light on how certain types of comets influence the lopsided bombardment of Mercury’s surface by tiny dust particles called micrometeoroids. Mercury, our…
