New Study Reassesses Habitability of Exoplanets Around Multiple Star Systems

An artist’s concept of Kepler-47, which was the first-ever planetary system to be discovered orbiting a binary star. A new research that was based on data taken with NASA’s Hubble Space Telescope provides stringest limits to the potential habitablity of exoplanets in several such systems.

One defining scientific revolution of […]

Cloudy With a Chance of Sunshine: Astronomers Study Weather on Distant Exoplanets

An artist’s rendering of the possible weather and atmospheric circulation patterns on hot Jupiters. A new research by a team of astronomers that was based on data taken with NASA’s Kepler space telescope, studied the phase variations that occur as different portions of these planets are illuminated by their host stars as seen from […]

Building Blocks of DNA Can Potentially Be Created in Space, According to New Study

An artist’s impression of the material that has been ejected from the Supernova 1987A in the neighboring Large Magellanic Cloud. The violent deaths of stars during supernova exoplosions, expel most of the stellar material into interstellar space, reseeding it with large amounts of dust as well as complex organic compounds which form the basis […]

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

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, since […]

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 the […]

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 Nuclear Spectroscopic Telescope […]

Worlds Beyond Our Own: Celebrating 25 Years of Hubble Science (Part 3)

A stunning image of a giant cluster of about 3,000 stars, called Westerlund 2, which lies approximately 20,000 light-years away from Earth. This image was officially selected by NASA to commemorate the 25th anniversary since the launch of the Hubble Space Telescope, on April 24, 1990.

Shedding New Light On the Solar System: Celebrating 25 Years of Hubble Science (Part 2)

A series of images of Uranus and Neptune that were taken with the Hubble Space Telescope. The top row reveals the ice giant planets in natural colors, showing the planets as they would appear if we could see them through a telescope. The images at the bottom were taken with certain types of different […]
