A hypnotising view of Paranal

An open white dome, with part of a telescope peeking through its opening at the top. The sky in the background is full of concentric white-ish circles, centered at the top of the telescope.

A hypnotising view of Paranal in #Chile!

Capturing these circular star trails is no easy task: a slight misalignment can completely ruin the outcome! 😲

For the first time ever, astronomers have unveiled the shape of a star’s explosion at its earliest stage.

The feat was achieved by ESO's Very Large Telescope just a day after the detection of this supernova, as the blast was breaking through the star’s surface.

This brief initial phase wouldn’t have been observable a day later. This will help shed light on how massive stars go supernova.

Swift observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the explosive death of a star just as the blast was breaking through the star’s surface. For the first time, astronomers unveiled the shape of the explosion at its earliest, fleeting stage. This brief initial phase wouldn’t have been observable a day later and helps address a whole set of questions about how massive stars go supernova.

Unique shape of star’s explosion revealed just a day after detection

Beautiful and colorful photo of an aurora over a lighthouse.

Seeing the #NorthernLights from my apartment balcony! And this is from downtown - I can only imagine how vibrant it would be if I drove an hour outside of town!

Shot on a Nikon D5300 with 18-58mm lens.

A photo of the Northern Lights. There is a large pink-red wisp throughout the center and upper left of the frame. Blue-green sky lines the bottom, while the normal, dark blue-blue night sky lines the right. There is minimal cloud cover, and a decent amount of stars are visible throughout the frame.

And here’s a timelapse! Zero editing on the photos though (for now). This was towards the end of their major activity in my area, so it’s kinda dark. Still fun though!

A dance of two pairs!

While the two Magellanic Clouds shine upon the Atacama Desert in #Chile, two Auxiliary Telescopes of ESO’s Very Large Telescope Interferometer point up to the sky.

Just like our cosmic neighbours move around the Milky Way, the Auxiliary Telescopes can be moved along rails and arranged in different configurations when observing the sky.
