For several years now the Kepler Space Telescope, as well as other telescopes, has been discovering an increasing number of exoplanets, with over 2,000 such confirmed worlds found so far (and nearly 5,000 candidates). […]

Development of Freeform Optics Technology May Revolutionize Space Telescopes

In the world of telescopes, light gathering power is dictated by the physical size of the first mirror or lens exposed to […]

Planets Around Red Dwarf Stars Could Be More Life-Friendly Than Previously Thought, According to New Study

An artist’s concept of a hypothetical terrestrial exoplanet with two moons orbiting inside the habitable zone of a red dwarf star. New research has shown that such planets could under the right conditions generate their own magnetic field, which could render them potentially habitable. Image Credit: D.

Astronomers Trace Spiral Structure of Milky Way With WISE

Using data from NASA’s WISE spacecraft, astronomers were able to trace the shape of our Milky Way galaxy’s spiral arms, by revealing the presence of hundreds of open clusters of very young stars shrouded in dust, called embedded clusters, which are known to reside in spiral arms. The image shows the location of […]

Event Horizon Telescope Provides New Evidence for Existence of Black Holes

A recent study, which was undertaken with the help of the Event Horizon Telescope, has provided new indirect evidence that indeed this is the case. Image Credit: ESO/L. Cal├žada

Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, […]

NASA Space Telescope Sees Possible X-Ray 'Screams' From Zombie Stars

It sounds like something from a bad sci-fi movie, but a NASA space telescope has detected what might be the X-ray “screams” from dead (zombie) stars. The […]

Orbiting Rainbows: Using 'Glitter Clouds' to Search For and Image Exoplanets

The search for exoplanets may one day get a lot more glittery. It sounds a bit like science fiction, but a new NASA proposal called Orbiting Rainbows would use glitter-like materials to help image some of those far-away worlds, which could enable high-resolution imaging at a fraction of the cost.

Spitzer Space Telescope Discovers Distant Exoplanet Across the Milky Way

Utilising NASA’s Spitzer Space Telescope, astronomers have discovered a distant exoplanet located 13,000 light-years away, through gravitational microlensing. The red cone in the map above our Solar System, depicts the extend in the galaxy of the thousands of known exoplanets that have been discovered by NASA’s Kepler space telescope, while the red circle […]
