China launches 14 commercial satellites into orbit atop Long March 2D rocket (video)

China has 14 new satellites in orbit following its fifth launch of 2023. A Long March 2D rocket lifted off from the Taiyuan Satellite Launch Center in northern China on Saturday (Jan. 14) at 10:14 p.m. EST (0314 GMT or 11:14 a.m. Beijing time on Jan. 15). Insulation tiles fell from the rocket as pink and purple exhaust propelled it above the frosty surrounding hills of Taiyuan. Aboard were 14 satellites for a range of customers. Six of the payloads were Jilin-1 optical and infrared remote sensing satellites for a…

Brilliant green comet loses part of its tail to solar storm in this stunning astrophotographer photo

An image taken by an Austrian comet hunter reveals a disconnection in a stunning green comet’s tail that may have been caused by turbulent space weather.  Seasoned astrophotographer Michael Jäger took this image of the Comet C/2022 E3 (ZTF) on Tuesday (Jan. 17) after driving 500 miles (800 kilometers) from Austria to Bavaria in Germany to get a clear view of the night sky. Jäger shared the image on Twitter (opens in new tab), along with more photos video of the comet. “The journey was not in vain,” Jäger told…

3.3 billion Milky Way objects revealed by colossal astronomical survey

An ambitious new survey of the Milky Way’s galactic plane has revealed 3.32 billion cosmic objects in stunning detail.  The enormous celestial catalog, possibly the largest of its type, was built using data from the Dark Energy Camera at the Cerro Tololo Inter-American Observatory in Chile, which is operated by the U.S. National Science Foundation (NSF).  “Imagine a group photo of over three billion people and every single individual is recognizable!” Debra Fischer, division director of Astronomical Sciences at the NSF, said in a statement (opens in new tab). “Astronomers…

‘Absolutely bonkers’ aurora lights up the sky above Iceland (video)

An Icelandic room reservation paid off big for a student “aurora chaser.” Vincent Ledvina traveled halfway across the world from Alaska to Iceland and spotted surges of green auroras the night of Jan. 13, right over his cabin, cataloging a terabyte’s worth of “absolutely bonkers (opens in new tab)” northern lights footage about two hours from Reykjavík. “This particular […] location was legendary and led to some of my favorite aurora compositions ever,” said Ledvina in a tweet (opens in new tab); he is no stranger to the shimmering green…

Newfound ultra-faint dwarf galaxies are ‘pristine fossils of the early universe’

Three ultra-faint dwarf galaxies have been discovered around a distant spiral galaxy with a mass similar to the Milky Way. The dwarf galaxies are believed to be around 12 billion years old, meaning their stars formed early in the universe’s history, under 2 billion years after the Big Bang.  At a distance of around 11.4 million years away from Earth, the ultra-faint galaxies are the first to be found orbiting a Milky Way-like galaxy outside of our galaxy’s cosmic backyard, known by astronomers as its “Local Group” which includes Andromeda…
