You’re looking at a 300-megapixel photo of our Sun. Astrophotographer Andrew McCarthy used a specially modified telescope, taking over 150,000 individual photos and combing them into this magnificent image.
“It took about 10 hours to stack all the data, and another 3-4 hours to get it from a raw stack to the final image,” McCarthy said via email.
Vivid green and purple aurora swirled and danced across the entire night sky in Sweden recently. The nighttime light show was captured by an all-sky camera in Kiruna, Sweden, which is part of the European Space Agency’s (ESA) Space Weather Service Network.
A group of amateur and professional astronomers have collaborated to create what may be the highest resolution global map of Mars ever created with images taken from Earth.
The images were taken with the 1-meter telescope at the Pic-du-Midi observatory in the Pyrenees of France, during several nights in October and November, 2020 when Mars was at opposition, or its closest approach to Earth.
There’s always more than one way to look at the world. There’s also more than one way to look at a galaxy. And sometimes combining those ways of looking can result in something truly special.
That is what happened recently when a team of astronomers from seven different universities in four different countries used three different telescopes to produce an absolutely spectacular image of a galaxy and its surrounding magnetic field.
Photographer Eric Brummel has created a stunning time-lapse of the Milky Way. Time-lapses of the Milky Way are not rare, but Eric has turned convention on its head. Instead of the Milky Way moving across the night sky, it’s the Earth that’s in motion.
The SPHERE planet-hunting instrument on the European Southern Observatory’s Very Large Telescope captured this image of a white dwarf feeding on its companion star, a type of Red Giant called a Mira variable. Most stars exist in binary systems, and they spend an eternity serenely orbiting their common center of gravity. But something almost sinister is going on between these two.
Astronomers at the ESO have been observing the pair for years and have uncovered what they call a “peculiar story.” The Red Giant is a Mira variable, meaning it’s near the end of its life, and it’s pulsing up to 1,000 times as bright as our Sun. Each time it pulses, its gaseous envelope expands, and the smaller White Dwarf strips material from the Red Giant.
