If you were to lick the surface of Jupiter‘s icy moon Europa, you would actually be sampling a bit of the ocean beneath – at least that’s what a new paper by Mike Brown, an astronomer at the California Institute of Technology in Pasadena, Calif., and Kevin Hand from NASA’s Jet Propulsion Laboratory concludes. Their [...]

Researchers have, for the first time, calculated the distance to the Large Magellanic Cloud, a galaxy neighboring the Milky Way. Care to take a guess? According to these calculations, it’s just 163.000 light-years away. For measurements inside our solar system, researchers use a technique called parallax. Parallax is a displacement or difference in the apparent [...]

A ring of radiation that scientists knew nothing about fleetingly surrounded our planet last year, before being blown away by a powerful interplanetary shock, researchers say. Astronomic intuition Usually, whenever NASA launches a spacecraft, they wait weeks or even months to finely tune all its instruments. It’s a rite of passage that all shuttles (and [...]

Most of us likely own a phone  that has more computing power than that available for the entire Apollo mission which landed a man on the moon, still rather curiously we choose to dedicate most of it to browsing photos of cute cats on the web. Nevertheless, there comes a time when pedestrian technology can [...]

A metal poor star located in the Milky Way galaxy, “just” 190 light years away from our Sun is 14.46+-0.80 billion years old – nearly as much as the age of the Universe! All stars follow a stellar evolutionary path; by knowing some parameters about the star (such as mass, luminosity, and surface temperature), astronomers [...]

According to a new study, the generally accepted theory on lunar formation may have to be reexamined. A relatively recent study has found water in the Moon’s original crust, which means that water found in those rocks didn’t come from an outside source, but was already there when the Moon was formed – something impossible, [...]

NASA’s Kepler telescope is on a roll – recently, astronomers working on it discovered a new planetary system that is home to the smallest planet yet found orbiting a star similar to our sun. A similar star, a different system The planets are located in a system researchers call Kepler-37, just over 200 light years, [...]

During a chance encounter with an unusually strong blast of solar wind at Saturn, NASA’s Cassini spacecraft detected particles being accelerated to ultra-high energies (like those at the LHC); this acceleration is similar to that which takes place around distant supernovas and provides a valuable in-situ study environment. The Cassini spacecraft is an absolutely stunning [...]

So, remember that Higgs boson discovery we got all excited about a while ago? You know, validated the Standard model, proved our understanding of the subatomic world not wrong, and all that? Turns out, that same data could very well be an obituary for our Universe – at least that’s what Joseph Lykken of the [...]

It was a mystery that kept astronomers scratching their heads for years, but now, it finally seems to be cracked: particles from inside the solar system bounce off a “ribbon” of energy boundary and neutral atoms from that collision stream inward. Why and how this happens remained a mystery for quite a while. Basically, this strange [...]
