Check Out This Mesmerising Timelapse of the Night Sky Above Hawaii

Telescopes dot the cloudless top of the dry volcano Mauna Kea in Hawaii, Earth’s tallest mountain from its underwater base to its peak. Its night skies, free of artificial light, are a resource disappearing across the planet in the face of light pollution. Read More >>

Did Prehistoric People Watch the Stars Through This 6,000 Year Old ‘Telescope’?

Prehistoric humans may have observed the sky via primitive lens-less “telescopes”, according to a team of British astronomers who have studied the long passageways of ancient megalithic tombs. The details were presented today by Kieran Simcox, a student at Nottingham Trent University, at a meeting of the Royal Astronomical Society. Read More >>

Stephen Hawking Backs $100m Search for Aliens

The Breakthrough Listen project is our latest attempt to see if any other civilisations have made it through the Great Filter without destroying themselves in radioactive fires, investing $100m (£64m) in the neverending hunt for aliens clever enough to have invented telly and satellites.

Why You Should Thank an Astronomer for Preventing Blindness

We are, as Carl Sagan famously said, made of star stuff. And now, your doctor may use a technology designed for studying the stars to examine the inner workings of your eyes. It could one day save you from blindness – here's how it works. Read More >>

The Ageing Giant of Telescopes, Shrouded in Tropical Mist 

The Arecibo Observatory in Puerto Rico is one of the most famous telescopes in the world: it’s been in a James Bond film (GoldenEye) as well as Contact. Now that the telescope is ageing, though, it’s only looking more dramatic. Read More >>

The Pillars of Creation Will Disappear in a Cosmic Blink

One way or another, the Pillars of Creation are toast. Based on new observations at the European Southern Observatory, these awe-inspiring structures have another three million years before their ghostly image fizzles away into cosmic nothingness. Read More >>

This Telescope Is Shooting a Laser Right at the ISS

Who gave this telescope a lightsaber? Just kidding: this is, of course, the ESA's Optical Ground Station telescope in Tenerife -- in the process of laser tagging the International Space Station to establish a data connection. Read More >>

NASA’s New Recoverable Telescope Will Float Above the Clouds by Balloon

Both terrestrial telescopes and their orbital counterparts have some pretty significant limitations—ground based observatories must deal with the obscuring effects of the Earth's atmosphere and space telescopes are incredibly expensive to launch. But NASA's newest telescope will deliver space-quality observations at a Earth-bound 'scope price. Read More >>

The Plan to Make the Moon an Enormous Detector of Cosmic Rays

About once a century on any given square kilometre of Earth, a cosmic ray hits with mind-boggling intensity. The teeny tiny subatomic particle from space comes careening in with more than 10 million times the energy of particles shot out by the LHC. Where do these ultrahigh energy cosmic rays come from? Astronomers have a plan to find out, using the moon and a massive new radio telescope array. Read More >>

The World’s First Fully Robotic Telescope is Hunting for New Earths

Tracking down Earth-like exoplanets with a terrestrial telescope is no easy feat because our planet's atmosphere makes distant solar systems even harder to see. Adaptive optic technology can help make things go a little faster, but it does so at a snail's pace—requiring up to 10 minutes per target. The fully autonomous Robo-AO system, however, lets any telescope lock on to targets in just 60 seconds. Let the hunt for Earth 2.0 begin! Read More >>
