“Space is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down […]

Size Matters: Astronomers Discover Rare, 'Super Spiral' Galaxies

A team of astronomers has recently discovered a total of 53 ‘super spiral’ galaxies which are enormous in size, three of which are shown in the image above. The galaxies shown at the left and center images also exhibit a double nucleus, which could be the result of a past galactic merger. Image […]

Development of Freeform Optics Technology May Revolutionize Space Telescopes

Peering ever further back in space and time, the Hubble Space Telescope has glimpsed the largest known group of the faintest and youngest primordial galaxies ever—over 250—some of which are […]

Event Horizon Telescope Provides New Evidence for Existence of Black Holes

An artist’s impression of a supermassive black hole. Astronomers believe that such objects lie at the centers of most galaxies in the Universe. 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. Calçada

It’s […]

To the Edge of Time: Celebrating 25 Years of Hubble Science (Part 4)

The breathtaking image of the Hubble eXtreme Deep Field, which was created from data that had been collected with the Hubble Space Telescope in 2003 and 2004. In order for the image to be created, the space telescope pointed towards a small patch of the sky for a total of 50 days, while […]

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