Before sunrise on October 8, the bright full moon over North America will turn a lovely shade of red. It’s a total lunar eclipse that’s visible from all parts of the U.S.
Astronomical imagery often figured in the poetry of Pablo Neruda. Today, with the help of Michael West of Maria Mitchell Observatory, we honor that connection.
NASA’s MAVEN spacecraft – first spacecraft dedicated to exploring Mars’ upper atmosphere – successfully entered orbit on September 21, 2014 at 10:24 p.m. EDT.
On the day of the equinox, the center of the sun would set about 12 hours after rising – given a level horizon, as at sea, and no atmospheric refraction.
A lunar tetrad – four total lunar eclipses in a row – began on the night of April 14-15. The next one will be on the night of October 7-8.
It’s an unlikely object in an improbable place — a monster black hole lurking inside one of the tiniest galaxies ever known.
A new and tantalizing hint of mysterious dark matter has been found by the Alpha Magnetic Spectrometer particle detector aboard the International Space Station.
A collision with a high-energy radiation particle may have corrupted software running in Dawn’s main computer, and sent the spacecraft into safe mode.
Here’s a collection of 10 unexpected, intriguing facts about the stars of our universe – including our sun – that you probably didn’t know!
As Voyager 1 left Earth on September 18, 1977, it looked back and acquired a stunning image.
The New Horizons spacecraft – due to encounter Pluto in July 2015 – has spotted Pluto’s small, faint, outermost known moon, called Hydra.
Astronomers thought mergers formed giant elliptical galaxies. Now, for at least 24 observed galaxies, mergers have formed flattened, circular disks of dust and gas.
Astronomers spent 10 years charting stars brighter than 20th magnitude – that’s about 1 million times fainter than can be seen with the human eye.
Rosetta spacecraft has been moving in tandem with its comet since August. On Monday, ESA announced the site of a November landing.
The first evidence for water-ice clouds on an object beyond our solar system. It’s a brown dwarf, one of our closest neighbors, only 7 light-years away.
Reports from NOAA and elsewhere predict a chance of significant auroras, possibly observable as far south as the northern U.S. and maybe even farther south.
Fire in space doesn’t act like fire here on Earth. Untethered by gravity, flames in space curl themselves into tiny balls.
An otherworldly take take on an earthly trend, as Rosetta poses with its comet, 67P/Churyumov–Gerasimenko.
New works suggests most observed quasar phenomena depend on two things: how efficiently a central black hole is being fed and the astronomer’s viewing orientation.
European cosmologists and particle physicists come together to tweak an accepted model of how cold dark matter helps build galaxies in our universe.
The comet turns out to be a unique, multifaceted world. We now know comets can have cliffs, depressions, craters, boulders or even parallel grooves.
