A team of Japanese astronomers has obtained a firm evidence of formatino of a giant planetary system around a young star by the observations with the Atacama Large Millimeter/submillimeter Array (ALMA). This result has a transformative impact on the theories of planet formation and gives us a clue to the origin of a wide variety of planetary systems.
The Chang'e-3 lunar probe has started its long-term scientific missions and will have its durability tested when it continues lunar surface surveys, sources with the Beijing Aerospace Control Center said on Thursday.
A comet-bound spacecraft that's been in sleep mode for more than two years is scheduled to wake up on the morning of Jan. 20 - beginning the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice.
The Monitor of All-sky X-ray Image (MAXI) collects data that help researchers discover, study and understand the physics behind the lifecycle of our universe. MAXI was key in two recent publications sharing results that make strides in advancing astrophysics.
Spanish scientists have discovered the first binary system ever known to consist of a black hole and a 'spinning' star - or more accurately, a Be-type star. Although predicted by theory, none had previously been found.
Harnessing the power of both the Hubble Space Telescope and the citizen science project Galaxy Zoo, scientists from the University of Portsmouth have found that bar-shaped features in spiral galaxies accelerate the galaxy aging process.
This new Hubble image is the best-ever view of a cosmic creepy-crawly known as the Tarantula Nebula, a region full of star clusters, glowing gas, and dark dust. Astronomers are exploring and mapping this nebula as part of the Hubble Tarantula Treasury Project, in a bid to try to understand its starry anatomy.
A photogenic and favorite target for amateur astronomers, the full beauty of nearby barred spiral galaxy M83 is unveiled in all of its glory in this Hubble Space Telescope mosaic image. The vibrant magentas and blues reveal the galaxy is ablaze with star formation. The galaxy, also known as the Southern Pinwheel, lies 15 million light-years away in the constellation Hydra.
A new study of light from quasars has provided astronomers with illuminating insights into the swirling clouds of gas that form stars and galaxies, proving that the clouds can shift and change much more quickly than previously thought.
Recent observations by NASA's Swift spacecraft have provided scientists a unique glimpse into the activity at the center of our galaxy and led to the discovery of a rare celestial entity that may help them test predictions of Albert Einstein's theory of general relativity.
An object discovered by astrophysicists at the University of Toronto nearly 500 light years away from the Sun may challenge traditional understandings about how planets and stars form. The object is located near and likely orbiting a very young star about 440 light years away from the Sun, and is leading astrophysicists to believe that there is not an easy-to-define line between what is and is not a planet.
Swirling, stormy clouds may be ever-present on cool celestial orbs called brown dwarfs. New observations from NASA's Spitzer Space Telescope suggest that most brown dwarfs are roiling with one or more planet-size storms akin to Jupiter's 'Great Red Spot'.
A team of scientists led by astronomers at the University of California, Riverside has used NASA's Hubble Space Telescope to uncover the long-suspected underlying population of galaxies that produced the bulk of new stars during the universe's early years. The galaxies are the smallest, faintest, and most numerous galaxies ever seen in the remote universe, and were captured by Hubble deep exposures taken in ultraviolet light.
After nearly a decade of development, construction, and testing, the world's most advanced instrument for directly imaging and analyzing planets around other stars is pointing skyward and collecting light from distant worlds.
