The Hubble Space Telescope has shared the sharpest view of the interstellar comet 2I/Borisov moving at 160 934 km/h (100 000 mph) past the Sun. This is the second interstellar object recorded in our solar system, the first being Oumuamua in 2017. "Hubble…
The Geminid meteor shower is expected to peak on December 14, 2019. At its peak, the shower can produce up to 120 multicolored meteors per hour. However, the Moon will be only 4 days past full phase at the shower's peak, presenting significant interference…
A brilliant fireball was seen streaking across the night sky over Arizona at around 04:26 UTC on December 7, 2019. Witnesses said the light appeared green, likely a "shooting star" but more than a quick flash that such phenomenon commonly produces. The…
NASA's exoplanet-tracking satellite Transiting Exoplanet Survey Satellite (TESS) captured a rare glimpse of the entirety of a "comet outburst"– an epic cosmic event where a comet spontaneously combusts in an intense explosion. This is the most…
A long-lasting fireball was seen flying through the sky over Alabama at around 01:31 UTC on December 5, 2019. The National Weather Service (NWS) in Birmingham was able to catch footage on its Skycam. NWS Birmingham said they received reports of a "vivid and…
NASA's Parker Solar Probe surprised scientists with its groundbreaking views of the Sun as the first results from the mission were released on Wednesday, December 4, 2019. Scientists observed bursts of energetic particles never seen before on a small scale, and…
A new study suggests that fireball that exploded over Australia in 2016 might have been Earth's 'minimoon.' If true, this would be the second observation of a minimoon fireball ever. Objects gravitationally captured by the Earth – Moon system are…
Scientists were left puzzled after a mysterious radio signal– observed near the Southern Constellation of Ara using the MeerKAT telescope– suggests a new type of star system in the Milky Way. About two months using the radio telescope based in the Karoo desert in…
When a massive dust storm on Mars– like the one in 2018– reaches its full potential, it can transform into a globe-bestriding colossus. This happens often on the red planet, and these storms typically start out as a sequence of smaller storms. NASA scientists said…
December 2 – Pheonicid meteor shower. The Pheonicid meteor shower is active from November 28 to December 9, producing its peak rate of meteors around December 2. Over this period, there will be a chance of seeing Pheonicid meteors from anywhere where the…
