Astronomers have found some of the youngest stars ever seen, thanks to the Herschel space observatory, a European Space Agency mission with important NASA contributions.

A new study using data from NASA's Chandra X-ray Observatory points to the origin of a famous supernova. This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class of objects that are used to measure the rate of expansion of the Universe.

Oreo's "Out of this World" Global App

"After conquering the seventh continent in its 100th birthday year, the World's Favorite Cookie has decided to take on the universe in its 101st with a new, ground-breaking star chart messaging app; OREO Skies. Putting its own, playful twist on traditional mobile messaging, OREOteamed up with Nokia to develop a smartphone app designed to connect people in a never-been-done before way: through the stars. Using augmented reality technology, the OREO Skies mobile app, now available exclusively onNokia Lumia Windows smartphones, allows users to ignite the "child" inside by writing messages and attaching them to actual constellations revealed in the app. As the best-selling global cookie brand,OREO is offering people around the world a chance to connect with each other in a way that's never been done before."

The U.S. National Science Foundation (NSF), in collaboration with its Canada and Taiwan partners, Japan, Europe and Chile, inaugurated the Atacama Large Millimeter/submillimeter Array (ALMA) today, one of the world's most powerful telescopes, as part of an international ceremony in Chile.

Researchers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through the blinding light of stars.

NASA's Wide-field Infrared Survey Explorer (WISE) has discovered a pair of stars that has taken over the title for the third-closest star system to the sun. The duo is the closest star system discovered since 1916.

This image compresses the Vela movie sequence into a single snapshot by merging pie-slice sections from eight individual frames.

Two X-ray space observatories, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton, have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our Sun.

The Birth of a Giant Planet?

Astronomers using ESO's Very Large Telescope have obtained what is likely the first direct observation of a forming planet still embedded in a thick disc of gas and dust. If confirmed, this discovery will greatly improve our understanding of how planets form and allow astronomers to test the current theories against an observable target.

The Whirlpool Galaxy

The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky.

Even dying stars could host planets with life -- and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Researchers found that we could detect oxygen in the atmosphere of a white dwarf's planet much more easily than for an Earth-like planet orbiting a Sun-like star.

"This article describes a citizen-science project conducted by the Spanish Virtual Observatory (SVO) to improve the orbits of near-Earth asteroids (NEAs) using data from astronomical archives. The list of NEAs maintained at the Minor Planet Center (MPC) is checked daily to identify new objects or changes in the orbital parameters of already catalogued objects. Using NEODyS we compute the position and magnitude of these objects at the observing epochs of the 938 046 images comprising the Eigth Data Release of the Sloan Digitised Sky Survey (SDSS). If the object lies within the image boundaries and the magnitude is brighter than the limiting magnitude, then the associated image is visually inspected by the project's collaborators (the citizens) to confirm or discard the presence of the NEA. If confirmed, accurate coordinates and, sometimes, magnitudes are submitted to the MPC." More

This image shows an object known as HH 151, a bright jet of glowing material trailed by an intricate, orange-hued plume of gas and dust. It is located some 460 light-years away in the constellation of Taurus (The Bull), near to the young, tumultuous star HL Tau.

The Large Sagittarius Star Cloud

This part of the constellation of Sagittarius (The Archer) is one of the richest star fields in the whole sky -- the Large Sagittarius Star Cloud.

Supernova Remnant W49B

The highly distorted supernova remnant shown in this image may contain the most recent black hole formed in the Milky Way galaxy. The image combines X-rays from NASA's Chandra X-ray Observatory in blue and green, radio data from the NSF's Very Large Array in pink, and infrared data from Caltech's Palomar Observatory in yellow.

Mercury Rising: Pink Planet at Sunset

The planet Mercury is about to make its best apparition of the year for backyard sky watchers. Look west at sunset for a piercing pink planet surrounded by twilight blue.

Andromeda's Colorful Rings

The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation.

Solving The Solar Corona Puzzle

The Sun's visible surface, or photosphere, is 10,000 degrees Fahrenheit. As you move outward from it, you pass through a tenuous layer of hot, ionized gas or plasma called the corona. The corona is familiar to anyone who has seen a total solar eclipse, since it glimmers ghostly white around the hidden Sun.

Betelgeuse Braces for a Collision

Multiple arcs are revealed around Betelgeuse, the nearest red supergiant star to Earth, in this new image from ESA's Herschel space observatory. The star and its arc-shaped shields could collide with an intriguing dusty 'wall' in 5000 years.

A nearby short-duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph Neuhauser.
