DM Tau has its own asteroid belt, and may be developing its own versions of Earth and Neptune, too. Continue reading Astronomers Peer at a Young Star System That Is Strikingly Similar to Our Own
“This discovery dramatically changes our view on the origin of fast-moving stars.” Continue reading This Runaway ‘Hypervelocity’ Star Was Catapulted from the Milky Way’s Disk
There’s something enchanting about ancient tools and instruments. The idea that our forebears were able to fashion precision mechanisms with nothing but the simplest hand tools is fascinating. And watching someone recreate the feat, such as by building an astrolabe by hand, can be very appealing too.
The astrolabe is an ancient astronomical tool of incredible versatility, allowing the user to do everything from calculating when the sun will rise to predicting the positions of dozens of stars in the night sky. That it accomplishes all this with only a few moving parts makes it all the more fascinating. [Uri …read more

Researchers from Clemson University used almost a decade of gamma ray data to map the entire observable universe for the very first time. Continue reading This is How Many Photons Are in the Entire Observable Universe
“Once we figure out, or I hope we figure out, that we are not alone in the universe, the connection to the cosmos is just going to be even stronger.” Continue reading Scientists Design a ‘Template’ for Plant Life on Alien Worlds
Korean royal astrologers saw a new star appear in the sky in 1437 AD, and it took 600 years for astronomers to find what they had seen, and explain why it appeared that night. Continue reading It Took 600 Years to Figure Out This Mysterious, Exploding Ancient Star
Astronomers have been watching the full fallout of a tidal disruption event for years. Continue reading A Black Hole Has Been Shredding a Star Twice the Size of the Sun for 10 Years
Astrophotography is one of those things you naturally assume must be pretty difficult; surely something so awesome requires years of practice and specialized equipment which costs as much as your car. You shake your fist at the sky (since you have given up on taking pictures of it), and move on with your life. Another experience you’ll miss out on.
But in reality, dramatic results don’t necessarily require sticker shock. We’ve covered cheap DIY star trackers before on Hackaday, but this design posted on Thingiverse by [Tinfoil_Haberdashery] is perhaps the easiest we’ve ever seen. It keeps things simple by using …read more
