Phoenicis Lacus region of Mars
Mars digital-image mosaic merged with color of the MC-17 quadrangle, Phoenicis Lacus region of Mars. Two of the four largest shield volcanoes on Mars are within the northwestern part, the south half of Pavonis Mons and Arsia Mons. The eastern part includes Syria and Sinai Plana. Most of the...
Kepler-10b: A Scorched World
Kepler-10b is a scorched world, orbiting at a distance that's more than 20 times closer to its star than Mercury is to our own Sun. The daytime temperature's expected to be more than 2,500 degrees Fahrenheit, hotter than lava flows here on Earth. Intense radiation from the star has...
The Lagoon Nebula
Like a Dali masterpiece, this image of Messier 8 from the NASA/ESA Hubble Space Telescope is both intensely colourful and distinctly surreal. Located in the constellation of Sagittarius (The Archer), this giant cloud of glowing interstellar gas is a stellar nursery that is also known as the Lagoon Nebula.Although...

NGC 4424 & LEDA 213994 Galaxies
Some astronomical objects have endearing or quirky nicknames, inspired by mythology or their own appearance. Take, for example, the constellation of Orion (The Hunter), the Sombrero Galaxy, the Horsehead Nebula, or even the Milky Way. However, the vast majority of cosmic objects appear in astronomical catalogues, and are given...
Extreme Planets
This artist's concept depicts the pulsar planet system discovered in 1992 using the Arecibo radio telescope in Puerto Rico. Three pulsar planets - the first of any kind ever found outside our Solar System - circling a pulsar called PSR B1257+12. Pulsars are rapidly rotating neutron stars, which are...
The south pole of Jupiter
This enhanced-color image of Jupiter's south pole and its swirling atmosphere was created by citizen scientist Roman Tkachenko using data from the JunoCam imager on NASA's Juno spacecraft.Juno acquired the image, looking directly at the Jovian south pole, on February 2, 2017, at 6:06 a.m. PST (9:06 a.m. EST)...

Cyclone Debbie
On March 28 at 03:42 UTC (1:42 p.m. AEST Queensland local time /Mar. 27 at 11:42 p.m. EST) NASA-NOAA's Suomi NPP satellite captured this visible image of Tropical Cyclone Debbie over eastern Australia.Before Debbie made landfall, NASA's Aqua satellite analyzed the temperatures in the storm on Mar. 27 at...
Stars Born in Winds from Supermassive Black Holes
Artist’s impression of a galaxy forming stars within powerful outflows of material blasted out from supermassive black holes at its core. Results from ESO’s Very Large Telescope are the first confirmed observations of stars forming in this kind of extreme environment. The discovery has many consequences for understanding galaxy...
Milky Way Galaxy seen over VLT’s four 8.2-metre Unit Telescopes
ESO's Very Large Telescope (VLT) looks more like a very small telescope in this image! From this perspective, it is difficult to make out the silhouettes of the VLT’s four 8.2-metre Unit Telescopes, which sit atop Cerro Paranal in the Chilean Atacama Desert.The VLT’s location was very carefully selected....
CoRoT-2a: Star Blasts Planet With X-rays
This artist's representation shows the CoRoT-2 system, which is found about 880 light years from Earth. The system, which is estimated to be between 100 and 300 million years old, contains a star and a planet in close orbit around it. The separation between the star and the planet...

Hubble detects supermassive black hole kicked out of galactic core
The galaxy 3C186, located about 8 billion years from Earth, is most likely the result of a merger of two galaxies. This is supported by arc-shaped tidal tails, usually produced by a gravitational tug between two colliding galaxies, identified by the scientists. The merger of the galaxies also led...
Supernova Remnant N103B
This image, taken with the NASA/ESA Hubble Space Telescope, shows the supernova remnant SNR 0509-68.7, also known as N103B. N103B was a Type Ia supernova, located in the Large Magellanic Cloud — a neighbouring galaxy of the Milky Way. Owing to its relative proximity to Earth, astronomers observe the...

Adansonia Grandidieri
Adansonia grandidieri, sometimes known as Grandidier's baobab, is the biggest and most famous of Madagascar's six species of baobabs. This imposing and unusual tree is endemic to the island of Madagascar, where it is an endangered species threatened by the encroachment of agricultural land.Grandidier's baobabs have massive cylindrical trunks,...
Ceres' Shadowed Craters Over Time
This animation shows how the illumination of Ceres' northern hemisphere varies with the dwarf planet's axial tilt, or obliquity.In the first frame the northern hemisphere is shown when Ceres' obliquity is 2 degrees, which is the minimum tilt. Regions that remain in shadow are shown in blue. The illumination...
Mars Volcano, Earth’s Dinosaurs Went Extinct About the Same Time
New NASA research reveals that the giant Martian shield volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The last volcanic activity there ceased about 50 million years ago—around the time of Earth’s Cretaceous–Paleogene extinction,...

Interacting Galaxies NGC 3447
Some galaxies are harder to classify than others. Here, Hubble’s trusty Wide Field Camera 3 (WFC3) has captured a striking view of two interacting galaxies located some 60 million light-years away in the constellation of Leo (The Lion). The more diffuse and patchy blue glow covering the right side...
Protostar blazes and reshapes its stellar nursery
This image, taken by the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, shows glowing dust inside the protocluster NGC 6334I. Studying this star-forming cloud in the Cat’s Paw Nebula (NGC 6334) with both ALMA and the Submillimeter Array (SMA) in Hawaii astronomers could see that something dramatic had taken...
NASA's Swift Mission Maps a Star's 'Death Spiral' into a Black Hole
This artist’s rendering shows the tidal disruption event named ASASSN-14li, where a star wandering too close to a 3-million-solar-mass black hole was torn apart. The debris gathered into an accretion disk around the black hole. New data from NASA's Swift satellite show that the initial formation of the disk...
