(Phys.org)—It was a big week for space science, topping the news of course was a European spacecraft landing on comet 67P/Churyumov-Gerasimenko. The spectacular achievement by the washing-machine sized Philae probe was ...
Evidence of atomic nitrogen in interstellar gas clouds suggests that pre-life molecules may be present in comets, a discovery that gives a clue about the early conditions that gave rise to life, according to researchers from ...
When Deep Impact smashed into comet Tempel 1 on July 4, 2005, it released the ingredients of our solar system's primordial "soup." Now, astronomers using data from NASA's Spitzer Space Telescope and Deep Impact have analyzed ...
When a star like our sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, using the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile, researchers ...
The Rosetta orbiter spectrometer for ion and neutral analysis (ROSINA) instrument orbited comet 67P to revolutionize our understanding of cometary material composition. A key finding of the satellite was to explore the composition ...
In 2017, a mysterious comet dubbed 'Oumuamua fired the imaginations of scientists and the public alike. It was the first known visitor from outside our solar system, it had no bright coma or dust tail, like most comets, and ...
Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water ...
An international team of researchers studying material from the asteroid Ryugu returned to Earth by the Hayabusa-2 Japanese space probe has found evidence that the asteroid formed in an outer part of the solar system, near ...
An enormous comet—approximately 80 miles across, more than twice the width of Rhode Island—is heading our way at 22,000 miles per hour from the edge of the solar system. Fortunately, it will never get closer than 1 billion ...
As comets approach the Sun, they release gas and dust known to astronomers as cometary activity. For comets passing near or inside Earth's orbit, this activity slows over successive orbits. University of Oklahoma astronomer ...
