NASA’s Hubble Observes Exoplanet Atmosphere Changing Over 3 Years

By combining several years of observations from NASA’s Hubble Space Telescope along with conducting computer modelling, astronomers have found evidence for massive cyclones and other dynamic weather activity swirling on a hot, Jupiter-sized planet 880 light-years away. The planet, called WASP-121 b, is not habitable.

NASA Telescopes Start the Year With a Double Bang

A colorful, festive image shows different types of light containing the remains of not one, but at least two, exploded stars. This supernova remnant is known as 30 Doradus B (30 Dor B for short) and is part of a larger region of space where stars have been continuously forming for the past 8 to […]

Meet the Infrared Telescopes That Paved the Way for NASA’s Webb

The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. On Dec. 25, NASA will celebrate the two-year launch anniversary of the James Webb Space Telescope – the largest and most powerful space observatory in history. The clarity […]

Hubble Sights a Galaxy with ‘Forbidden’ Light

This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy.

NASA’s Fermi Mission Creates 14-Year Time-Lapse of the Gamma-Ray Sky

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA’s Fermi Gamma-ray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond. “The bright, steady gamma-ray glow of the Milky Way […]

NASA’s Hubble Presents a Holiday Globe of Stars

The billion stars in galaxy UGC 8091 resemble a sparkling snow globe in this festive Hubble Space Telescope image from NASA and ESA (European Space Agency). The dwarf galaxy is approximately 7 million light-years from Earth in the constellation Virgo. It is considered an “irregular galaxy” because it does not have an orderly spiral or […]

This new image of NGC 2264, also known as the “Christmas Tree Cluster,” shows the shape of a cosmic tree with the glow of stellar lights. NGC 2264 is, in fact, a cluster of young stars — with ages between about one and five million years old — in our Milky Way about 2,500 light-years away from Earth. The stars in […]

NASA’s Webb Identifies Tiniest Free-Floating Brown Dwarf

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable […]
