Anyone who's ever seen aircraft engaged in formation flying can appreciate the feat of staying highly synchronized while airborne.


Based on preliminary results from a new Gemini Observatory survey of 531 stars with the Gemini Planet Imager (GPI), it appears more and more likely that large planets and brown dwarfs have very different roots.


The Gemini Planet Imager (GPI), a dedicated planet-finding instrument at the Gemini South telescope in Chile, is concluding a 4-year survey - the GPI Exoplanet Survey (GPIES) - of 531 young, nearby stars searching for giant planets.

Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy: superflares.


When scientists first saw this structure on the images taken by their camera on the Dawn space probe, they could hardly believe their eyes


Designed to explore a metal asteroid that could be the heart of a planet, the Psyche mission is readying for a 2022 launch.


Three Expedition 59 crewmembers are getting ready to end their stay at the International Space Station after six and a half months in space. Meanwhile, mission scientists continue exploring how microgravity impacts the human body.


NASA astronaut Nick Hague assembles and installs the Water Storage System inside the U.S. Destiny laboratory module.


A mysterious large mass of material has been discovered beneath the largest crater in our solar system -- the Moon's South Pole-Aitken basin -- and may contain metal from the asteroid that crashed into the Moon and formed the crater, according to a Baylor University study.


If astronomers want to learn about how supermassive black holes form, they have to start small--really small, astronomically speaking.


Storm clouds are seen on the southwestern coast of Yemen as the International Space Station was about to fly 254 miles over the Bab al-Mandab Strait in between the Gulf of Aden and the Red Sea.


The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the impact rate of interstellar meteors of its size ∼100m.


Orion's service module for NASA's Artemis 1 mission was moved from a test stand to a test cell inside the Operations and Checkout Building at NASA's Kennedy Space Center in Florida on May 22, 2019.


This striking image was taken by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble's most breathtaking and iconic photographs.


NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.


The Copernicus Sentinel-2 mission takes us over Lake Valencia, in northern Venezuela.This false-colour image was processed in a way that makes vegetation of the Henri Pittier National Park, north of the lake, appear in fluorescent green. These bright colours contrast with the blackness of the lake.


The International Space Station's BEAM opened up today for environmental sampling and cargo stowage activities as NASA continues to test the commercial module. The Expedition 59 crew also explored biotechnology and fluid physics to improve Earth applications and space habitability.


The test version of Orion attached to the Launch Abort System for the Ascent Abort-2 (AA-2) flight test is moved by crane into the vertical integration facility at Space Launch Complex 46 at Cape Canaveral Air Force Station in Florida on May 23, 2019.


Without the sound advice of meteorologists and geologists working behind the scenes, one of the most consequential battles in human history could have gone quite differently.


Galaxies with no dark matter are impossible to understand in the framework of the current theory of galaxy formation, because the role of dark matter is fundamental in causing the collapse of the gas to form stars.


NASA's Mars Helicopter flight demonstration project has passed a number of key tests with flying colors. In 2021, the small, autonomous helicopter will be the first vehicle in history to attempt to establish the viability of heavier-than-air vehicles flying on another planet.


A new documentary on Apollo 8, "First To The Moon", by filmmaker Paul Hildebrandt has been released. I am not going to mince words: this is the finest space documentary I have ever seen. Full stop.


The SpaceX Dragon cargo craft on its 17th contracted mission to resupply mission to the International Space Station is pictured moments before being released from the Canadarm2 robotic arm.


New ALMA observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black hole at the center of the Milky Way.


Earlier in the week, NOAA's National Hurricane Center was monitoring a low-pressure system in the Gulf of Campeche that has now moved along the Texas and Louisiana coastlines, bringing heavy rainfall. On June 5, NASA used a constellation of satellites to estimate that rainfall.


A group of researchers has identified and characterized for the first time in a complete way a powerful eruption in the atmosphere of the active star HR 9024, marked by an intense flash of X-rays followed by the emission of a giant bubble of plasma, ie hot gas containing charged particles.


Revolutionary technology often comes in small packages. CubeSats - shoebox-size satellites - transformed what kind of science and computing we could accomplish in orbit around Earth and other planetary bodies.


In the summer of 2018, a dust storm blanketed the entire planet Mars. From the surface, the Sun would have looked like tiny orb in a murky brown sky.


SpaceX's Dragon cargo spacecraft splashed down in the Pacific Ocean at 5:48 p.m. EDT (2:48 p.m PDT), approximately 202 miles southwest of Long Beach, California, marking the end of the company's 17th contracted cargo resupply mission to the International Space Station for NASA.
