It is most likely to be a young star with a massive core that is still accreting material.
Dark matter does not slow down when colliding with each other, which means that it interacts with itself even less than previously thought.
The dwarf galaxy is the least abundant in metals in the nearby universe and one of the most akin to the primeval galaxies.
The finding validates a long-suspected feedback mechanism enabling a supermassive black hole to influence the evolution of its host galaxy.
The new work addresses why the terrestrial planets in our solar system have such relatively low masses compared to the exoplanets orbiting other Sun-like stars.
Scientists have long thought that nitrates would be produced on the Red Planet from the energy released in meteorite impacts, and the amounts they found agree with estimates from this process.
Observations reveal that a particular supernova produced a cloud that contains enough dust to make 7,000 Earths.
The observed outburst reveals a sudden accumulation of gas and dust.
The star, which astronomers saw appear in the sky in 1670, was not a nova, but a spectacular collision between two stars, more brilliant than a nova, but less so than a supernova.
Astronomers using NASA’s Chandra X-ray Observatory are studying nova GK Persei to provide clues to the dynamics of much larger stellar explosions.
New Horizons’ flyby past Pluto and its largest moon, Charon, will transform them from poorly seen hazy bodies to tangible worlds with distinct features.
The instrument has just begun to scour the sky for messages from other worlds.
The MESSENGER team initiated the “hover” observation campaign, which was designed to gather data from the planet at ultra-low altitudes until the last possible moment.
A team of astronomers and geologists have produced a new map of the Moon’s most unusual volcano showing that its explosive eruption spread debris over an area much greater than previously thought.
Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars.
Instead of core formation occurring by iron sinking down to the growing Earth’s core in large blobs, that iron was vaporized, spread out in a plume over the surface of Earth and rained out as small droplets.
This database gives us the first glimpse at what diverse worlds out there could look like.
The chemical variability revealed will provide critical constraints on future efforts to model and understand Mercury’s bulk composition and the ancient geological processes that shaped the planet’s mantle and crust
Analysis of images taken of our solar system’s main belt asteroids between Mars and Jupiter using a new algorithm showed a 15 percent increase in positive identification of new asteroids.
The Hapi region is located between 67P’s two lobes and has in the past months proven to be particularly active and the source of spectacular jets of dust and gas.
