While all previous hypervelocity stars are single, PB 3877 is the first wide binary star found to travel at such a high speed.
Mission operations engineers have successfully recovered the Kepler spacecraft from Emergency Mode.
Based on the signals seen so far and the sensitivity of LIGO's detectors, scientists estimate that they'll see between 10 and 100 black hole mergers during the instrument's next observing run, which begins in late summer.
Deep radio imaging has revealed that supermassive black holes in a region of the distant universe are all spinning out radio jets in the same direction.
While the proposed planet’s existence may eventually be confirmed by other means, mission navigators have observed no unexplained deviations in the spacecraft’s orbit.
NASA's Kepler mission will begin a search for planets orbiting far from their stars by using gravitational lensing.
By simulating the evolution of the interstellar ice making up comets, French research teams have successfully obtained ribose, a key step in understanding the origin of RNA — and therefore of life.
An international team of scientists has found evidence of a series of massive supernova explosions near our solar system, which showered the Earth with radioactive debris.
A team of astronomers has discovered one of the youngest and brightest free-floating, planet-like objects within relatively close proximity to the Sun.
Astronomers have uncovered a near-record-breaking supermassive black hole weighing 17 billion Suns.
Given scientists’ current understanding of how often galaxies merge, limits point to fewer detectable pairs of supermassive black holes than previously expected.
A massive impact could have temporarily increased the planet’s atmospheric pressure, periodically heating Mars up enough to “re-start” a dormant water cycle.
From its perch high on a ridge, the rover recorded an image of a martian dust devil twisting through the valley below.
While the precise nature of the system remains unclear, the data imply that it is unusual and exotic.
New research shows that the radio emission believed to be an afterglow actually originated from a distant galaxy's core and was unassociated with the fast radio burst.
