Now the spacecraft will begin its first search for new moons or rings that might threaten its passage through the Pluto system.
Dawn scientists can now conclude that the intense brightness of these spots is due to the reflection of sunlight by highly reflective material on the surface, possibly ice.
Astronomers have found the best proof yet that the mechanism that triggers core-collapse supernovae is inherently lopsided.
The discovery wouldn’t have been possible without the spacecraft flying incredibly close to the planet in the months before impact.
Though plentiful in and around many galaxies, newborn examples of globular cluster are vanishingly rare and the conditions necessary to create new ones have never been detected until now.
This gaseous atmosphere of our neighboring galaxy is about 1,000 times more massive than previously estimated and stretches halfway to the Milky Way.
Scientists think most of the observed activity on Enceladus represents curtain eruptions from the “tiger stripe” fractures, rather than intermittent geysers along them.
New research finds that water-rich asteroids similar to those found in our solar system are plentiful in the galaxy.
This burst of radiation was the most powerful so far this year and already has resulted in a radio blackout.
A team discovered an exceptionally luminous galaxy more than 13 billion years in the past; it existed so long ago that it appears to be only 100 million years old.
The ability to peek into the atmospheres of rocky “super-Earths” and observe conditions on their surfaces marks an important milestone toward identifying habitable planets outside the solar system.
Further observations by astronomers using the Green Bank Telescope revealed that this pulsar is part of only a handful of double neutron star systems.
Clear evidence now suggests that the heating mechanism depends on regular but intermittent explosive bursts of heat, rather than on continuous gradual heating.
Scientists have discovered an exoplanet with Saturn’s mass and Jupiter’s radius orbiting a small, cool star.
This finding may help astronomers understand how the largest black holes were able to grow so rapidly in the early universe.
