There are volcanoes erupting hundreds of millions of miles beyond Earth. And a NASA spacecraft is watching it happen.

The space agency’s Juno probe, which has orbited Jupiter since 2016, swooped by the gas giant’s volcanic moon Io last week, its last close planned flyby. The craft captured a world teeming with volcanoes, which you can see in the footage below.

“We’re seeing an incredible amount of detail on the surface,” Ashley Davies, a planetary scientist at NASA’s Jet Propulsion Laboratory who researches Io, told Mashable in February after a recent Io flyby. “It’s just a cornucopia of data. It’s just extraordinary.”

Yes, the Universe is expanding, but if you’ve ever wondered, ‘How fast is it expanding,’ the answer isn’t in terms of a speed at all.

An international team of astronomers has performed radio observations of a massive galaxy cluster known as ACT-CL J0329.2–2330, which resulted in the detection of a new radio halo in this cluster. The finding was reported in a research paper published April 5 on the pre-print server arXiv.

NASA is proposing to wind down its Chandra X-ray Observatory. And astronomers are pissed.

The idea of a static universe would mean our cosmos is eternal, and it isn’t expanding after all.

For the first time, astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life.

The jets of matter, expelled by stars deemed ‘cosmic cannibals’, were measured to travel at over one-third of the speed of light — thanks to a groundbreaking new experiment published in Nature today.

The study sheds new light on these violent processes, making clever use of runaway nuclear explosions on the surface of stars.
