This is the oldest star that astronomers have ever discovered

An international team of astronomers has identified the earliest known star in the Universe. Considered a "second generation star," it formed shortly after the Big Bang — some 13.7 billion years ago. » 2/10/14 12:00pm 2/10/14 12:00pm

Voyager 1 outlives the magnificent death of the sun in this…

Production studio PostPanic and director Mischa Rozema crafted this gorgeous bit of artificial space porn, Stardust, in memory of graphic designer Arjan Groot, who passed away in 2011. It envisions the journey of Voyager 1 as it moves ever farther from our sun and continues well beyond the lifespan of humanity. » 2/03/13 9:30am 2/03/13 9:30am

The Ultimate List of Reasons We Know the Earth is Definitely Round

In case you had any lingering doubts, here is some masterful cosmological/geological/geometrical instruction on our planet and its spherical — but not perfectly spherical — tendencies, courtesy of the ever-capable Henry Reich (better known as the creator, animator and narrator of MinutePhysics). Some great, if not… » 1/03/13 2:24pm 1/03/13 2:24pm

The Webcomic Guide to Black Body Radiation and the Colors of the Stars

Earlier this year, Jorge Cham of the webcomic PhD Comics explained the Higgs Boson by combining narration from physicists with his own artwork. In his latest video, The Fingerprint of Stars, Jon Swift, Ben Montet, and Melodie Kao of CalTech's John Johnson Exoplanets Laboratory explain why different stars appear to be… » 12/15/12 10:30am 12/15/12 10:30am

It's Full of Stars: 84 Million Stars of the Milky Way in 9 Billion…

It's impossible to capture the scale of our galaxy on your computer screen, but darned if the European Southern Observatory isn't going to try. The observatory has released a 108500×81500 pixel mosaic of the central parts of the Milky Way. You weren't planning on doing anything else with your weekend, right? » 10/27/12 1:00pm 10/27/12 1:00pm

This luminous time-lapse video captures star trails forming in the…

When cameras follow the paths of stars across the sky, they capture star trails, which look like glowing record grooves and give you a sense of the Earth's movement. Photographer Daniel Lowe spent two years collecting static images of star trails in western North Carolina, and collected them into one gorgeous video. » 10/06/12 3:00pm 10/06/12 3:00pm

Heat map of the Sun looks like something Monet would be proud of

NASA's Nicholeen Viall has developed a new visualization technique for studying the Sun's temperature fluctuations — and the eye-catching results are startlingly beautiful. Each color-coded area in Viall's composition represents the star's temperature shifts over the course of a 12-hour span. The new method could help … » 7/23/12 9:30am 7/23/12 9:30am

Intense magnetic fields around white dwarfs may instigate an entirely…

Scientists at the University of Oslo have discovered a completely new way for atoms to bond together — but these researchers won't be replicating the effect in the lab any time soon. The previously unknown bonding mechanism can only happen in the vicinity of white dwarfs where their intense density and spin creates… » 7/20/12 8:20am 7/20/12 8:20am
