The glow of the Milky Way -- our galaxy seen edgewise -- arcs across a sea of stars in a new mosaic of the southern sky produced from a year of observations by NASA's Transiting Exoplanet Survey Satellite (TESS). Constructed from 208...

A spectacular head-on collision between two galaxies fueled an unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope.



The interacting galaxy duo is...

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity.



The planet,...

A team of specialists from the University of Geneva has confirmed the existence of an exoplanet orbiting in the habitable zone of a neighboring sun.

On July 4, NASA’s Transiting Exoplanet Survey Satellite (TESS) completed its primary mission, a two-year-long survey that imaged about 75% of the starry sky. In capturing this giant mosaic, TESS has found 66...

In celebration of the 31st anniversary of the launching of NASA’s Hubble Space Telescope on April 24, 1990, astronomers aimed the renowned observatory at a brilliant “celebrity star,” one of the brightest...

TESS, the Transiting Exoplanet Survey Satellite, is NASA's newest exoplanet mission. Led by MIT, TESS will find thousands of new planets orbiting nearby stars. During its two year survey, TESS will watch a wide variety...

Dubbed Ariel, the spacecraft is expected to launch in 2029 on ESA’s new Ariane 6 rocket.

Dr. Amy Simon has always been fascinated with space. From a young age she dreamed of lifting off in the space shuttle, just like her hero, astronaut Sally Ride. Over the years her interest in space remained, and...

Space researchers have proposed building a network of radio antennas on the far side of the moon. <br/>

An international team of astronomers has reported what may be the first example of an intact planet closely orbiting a white dwarf, a dense leftover of a Sun-like star that’s only 40% bigger than Earth. The...

Shortly after the Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images....

How do we spot something as tiny and faint as a planet trillions of miles away? The trick is to look at the star! So far, most of the exoplanets – worlds beyond our solar system – we’ve found were detected by looking for tiny...

Three astronomers in NASA Goddard's Exoplanets and Stellar Astrophysics Laboratory discuss how Hubble's coronagraph and resulting images have helped scientists find planets orbiting distant stars.<b<b<br/>r/>r/>

Episode 2: An Unexpected Journey – With five servicing missions, upgraded instruments, and new ways of operating, Hubble is not the same telescope it was when it launched....

Observations of Jupiter's icy moon Europa from NASA's Hubble Space Telescope have revealed the presence of persistent water vapor — but, mysteriously, only in one hemisphere.



Europa harbors a vast ocean underneath...

WFIRST, the Wide Field InfraRed Survey Telescope, is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics. The telescope has a primary mirror...

By studying this mysterious planet, scientists could learn a great deal more about exoplanets, as well as the past, present, and possible future of our own. This video unveils this world and calls on current and future...

NASA’s Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the universe’s birth in the big bang—the farthest individual star...

NASA’s Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope have found a young Neptune-size world orbiting AU Microscopii, a cool, nearby M dwarf star surrounded by a vast disk of debris. The...

A second look at data from NASA's Hubble Space Telescope is reanimating the claim that the nearby star Fomalhaut hosts a massive exoplanet. The study suggests that the planet, named Fomalhaut b, is a rare and possibly unique...

After Hubble’s important gyroscopes began to fail, a Hubble emergency was declared and Servicing Mission 3 was quickly split into two separate launches. So on Dec. 19, 1999, the brave crew of space shuttle Discovery...

Our Milky Way’s central black hole has a leak! This supermassive black hole, over 4 million times more massive than our Sun, looks like it still has the remnants of a blowtorch-like jet dating back several thousand...

NASA’s Hubble Space Telescope has given astronomers their best look yet at an interstellar visitor – Comet 2I/Borisov – whose speed and trajectory indicates it is from outside of our solar system.



This Hubble...
