Hubble image of close passage of Comet Siding Spring near Mars. The comet passed Mars at about a third the distance between Earth and the moon on October 19.
The latest science media releases highlighting exciting news and research from around the globe.
Astronomers have observed signals from a highly magnetized neutron star, indicating starquakes that set the neutron star ringing like a bell.
Get out your 3D glasses and watch a flyover of the weird landforms on Mars know as chaotic terrain.
Less solar activity indicates a weaker magnetic field on the sun. A weak field lets cosmic rays into the solar system, posing a radiation hazard for astronauts.
Two cool nighttime photos by astronauts aboard the ISS. Check out the bright city lights.
A team of astronomers has created the first three-dimensional map of the adolescent universe, just 3 billion years after the Big Bang.
Weather permitting, almost everyone in North America will be able to see the partial solar eclipse this Thursday.
A sight never seen before in recorded history … an encounter between Mars and a close-passing comet on October 19, 2014.
Scientists say that the tsunami that hit Japan in 2011 was a thousand-year event. A monster wave might strike Hawaii about as often.
The fabled quinary or 5th order rainbow is made by sunlight reflected five times inside raindrops. Now, for the first time, we have an image of one.
Here’s a 2-minute video on the comet’s October 19 near-miss of Mars, and how orbiting spacecraft will evade onslaught of dust particles from the comet.
Astronomers have discovered that our nearest galactic neighbors are devoid of star-forming gas, and that our Milky Way is to blame.
Astronomers struggle to learn about super-Earths – bigger than our Earth, smaller than Neptune – the most common type of planet found by the Kepler spacecraft.
A study demonstrates that Earth’s last magnetic reversal – 786,000 years ago – happened in roughly the span of a human lifetime.
After a long search at the solar systems’ fringes, scientists say they have three possible targets for the New Horizons spacecraft after its July 2015 Pluto flyby.
Four urban sections of the San Andreas Fault system in Northern California have stored enough energy to produce major earthquakes, according to a new study.
Earth’s atmosphere is leaking into space, too, but only very, very slowly. Meanwhile, Mars is thought to have lost much of its atmosphere already.
Crocs are able to conduct highly organized game drives. They might be second only to humans in their hunting prowess, says a researcher.
New research suggests that during Earth’s last ice age – about 21,000 years ago – icebergs regularly reached South Carolina and even southern Florida.
Tunnels ending in light, your life flashing before you, out-of-body sensations. Near-death experiences merit further study without prejudice, these researchers say.
Australian astronomers say our Milky Way galaxy has only half the dark matter we thought it did. If so, it explains the shortage of Milky Way satellites.
