The ‘bow shock’ is the first boundary the solar wind encounters as it approaches planets or comets. From 2014 to 2016, ESA’s Rosetta orbiter studied...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) captured the radio image of 46P/Wirtanen on December 2, 2018, when the comet...
The NASA/ESA Hubble Space Telescope and NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) snapped stunning images of a short-period comet...
On Sunday, December 16, 2018, comet 46P/Wirtanen will make a close pass of Earth. The comet will be at its closest distance to our planet in over four...
As far back as 40,000 years ago (Upper Paleolithic), ancient people kept track of time using relatively advanced knowledge of astronomy.
