Picture of the Day: Monster Saturn Storm

Cassini has been circling Saturn for years, but it’s still revealing spectacular things about the planet. Violent weather provides a great spectacle on Earth, as long as it doesn’t actually destroy anything, but it’s nothing compared with what’s happening on Saturn.

Absense of light reveals exoplanet atmospheres

Exoplanets are uncanny. Some seem to have walked directly out of the best science-fiction movies. For example, we’ve discovered a planet consisting purely of water (GJ 1214b) and one with two suns (Kepler 16b). Some planets nearly scrape their host stars once every orbit, while others exist in darkness without a host star at all. The […]

Picture of the Day: Colliding binary star winds

An artist’s rendering of a colliding wind binary.     A colliding-wind binary is a binary star system in which the two members are massive stars that emit powerful, radiatively-driven stellar winds. The location where these two winds collide produces a strong shock front that can cause radio, X-ray and possibly synchrotron radiation emission. Wind […]

Picture of the Day: Orion

  Humans have been gazing at Orion for millennia, but they’ve never seen it as beautiful as this. Granted, we can’t actually see it like the photo above would suggest, as the fiery glow is only visible to telescopes tuned to submillimeter radio frequencies.

Earth and Moon’s water from same source

Water on the Moon came from the same source as our water on Earth, a new study suggests.   The discovery reported in the journal Science, implies some of Earth’s water was transferred to the Moon when it formed.   The Moon is thought to have formed by a collision between Earth and a Mars-sized […]

Picture of the Day: Venus

Artist’s impression of an active volcano on Venus. Results from a long-term study of Venus find evidence of a clear injection of sulphur dioxide into its upper atmosphere. One possible interpretation is that volcanic activity increased the sulphur dioxide component of the upper atmosphere, although an alternative is that a change in atmospheric circulation dredged […]

New Method of Finding Planets Scores Its First Discovery

Detecting alien worlds presents a significant challenge since they are small, faint, and close to their stars. The two most prolific techniques for finding exoplanets are radial velocity (looking for wobbling stars) and transits (looking for dimming stars). A team at Tel Aviv University and the Harvard-Smithsonian Center for Astrophysics (CfA) has just discovered an […]

Incredible show of fluid dynamics in Zero-G at the ISS

This new video from Chris Hadfield, commander of the International Space Station is pretty amazing.

Habitable Worlds? New Kepler planetary systems imaged

The Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the “habitable zone,” the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water. The Kepler-62 system has five planets; 62b, 62c, 62d, 62e and 62f. The Kepler-69 system has […]

If that title seems like an obvious statement to you, it’s ok… it seems pretty obvious to me too. But there are those who have been suggesting — for quite some time, actually — that earthquakes can be triggered or strengthened by solar activity; that, in fact, exceptionally powerful solar flares, coronal mass ejections, and […]

What are Multiple Universes? Explanation by Minutephysics

Multiverses are a popular trope in SciFi movies or literature and it’s easy to understand why, the idea is quite interesting and exciting.

Picture of the Day: Space Junk

The European Union has launched a new program to tackle the threat of space junk, which litters the corridors of Earth orbit.
