Stained Glass Solar System

Over at Deviant Art the creator Breath Art has posted some excellent images of the Planets as Stained Glass in his Solar System series. I am putting a few here to give you the idea, you can click one to go directly to that images page. These are absolutely amazing, you should go take a […]

The Entire Face of Jupiter

Damian Peach took a series of images of Jupiter between March 18th to 22nd this year, and put them together to create this video he calls The Entire Face of Jupiter. He posted it earlier this week, so I thought I would share it here.

Infinite Worlds: A Journey through Parallel Universes

Posted by the World Science Festival, this presentation is part of The Big Idea Series, and I could not stop watching it once I started. From the Big Bang to the Multiverse, they explore a wide range of ideas, all theoretically supported to some greater or lesser extent, and some of them even have some […]

Perseid Meteor Shower

The Perseid Meteor Shower is already under way, with peak viewing on the 12th and 13th of August. During the peak you can see one or two a minute, although even this far outside of the peak there will be a handful per hour, with the frequency going up steadily the closer we get. Meteor […]

Thermonuclear Art

NASA assembled this amazing video of the Sun in Ultra-HD (4K) from footage generated by the Solar Dynamics Observatory, or SDO, and added some tasty music by Lars Leonhard to it. On top of that, the folks at the NASA Goddard Space Flight Center decided to make this video public domain, posting it so it […]

APOD: Two Black Holes Merge

When LIGO detected the gravity wave signature of two black holes merging, it inspired the Simulating eXtreme Spacetimes Project to create this simulation of the event as it would have appeared to human eyes, and post it online. The Astronomy Picture Of the Day site maintained by the folks at NASA then picked it up, […]

SpaceX ORBCOMM-2 Launch and Return of First Stage

On December 21st SpaceX made history by bringing the first stage of a rocket launch safely back to Earth, as part of a mission that put 11 satellites in various orbits. What makes this important is the fact that being able to reuse the first rocket stage reduces the cost of going to space to […]

Geminid Meteor Shower

This year the Geminid meteor shower peaks on the 14th, but numbers will be high from December 13th through the 15th. If we get clear skies the viewing should include fainter meteors since the moon will not be overhead during the event, which means 60 to 100 visible per hour, or better than 1 a […]

The Fermi Paradox

In The Fermi Paradox — Where Are All The Aliens?, the team of designers, journalists and musicians who make up Kurz Gesagt want to make science look beautiful, and they succeed quite nicely. They also do an excellent job of explaining The Fermi Paradox, which questions why we have not been visited by aliens, or […]
