💥💥 Double detonation!

For the first time, astronomers have obtained visual evidence that a star met its end by blasting twice.

This was done by studying the centuries-old remains of supernova SNR 0509-67.5 with our Very Large Telescope. Led by the Univ. of South Wales, this shows some of the most important explosions in the Universe in a new light.

What happened exactly? Keep reading.

Grateful that it's only #raining water in my neighborhood today 😂

A vertical infographic titled “Rains on Different Worlds” showing types of rain. From left to right, the planets or moons and their corresponding rainfall are: Earth: Water rain, depicted with crashing ocean waves. Venus: Sulfuric acid rain, shown with thick orange clouds. HD 189733b: Glass rain, illustrated by red-hot storms and molten glass shards. Neptune: Diamond rain, with a dark, icy surface and distant planet in view. OGLE-TR-56b: Iron rain, represented with glowing molten iron streaming downward.

How it rains on different planets: what the science says

It rains water on Earth, but on Titan, it rains with methane. Find out how it rains on other planets.

The skies of Chile’s Atacama Desert, renowned as the darkest and clearest of the world, are now at risk from an industrial megaproject.

Electricity company AES Andes proposed to locate a large-scale industrial complex just a few kilometres away from our Paranal Observatory. If constructed, the resulting dust emissions, increased atmospheric turbulence, and especially light #pollution, would irreparably impact the capabilities for astronomical observation.

We urge the involved parties, specifically AES Andes, to work with the Government of #Chile to relocate this megaproject to a zone compatible with industrial development without jeopardising the skies of Paranal.

World's darkest and clearest skies at risk from industrial megaproject

On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment.

I took a picture of #jupiter this morning and I think it's my best one yet! The conditions were the best I've ever seen in my backyard in #purmerend, the Netherlands. Gear: Skywatcher Skymax 180 and ZWO asi 224MC-s. #astrodon #astrophotography

Draw a one centimetre square on your finger & hold it towards the Sun 👆

Now consider that some 60 billion neutrinos hit it every second, created by nuclear fusion in the solar core 500 seconds ago 🙀

Even if it’s nighttime & your finger has to point down through Earth’s surface – they don’t care 🙃

But if it makes you feel better, there are only about 2 solar neutrinos in each cubic centimetre of you at any given instant 🤷‍♂️

Well, plus another 300 from the Big Bang 😬
