Scientists find a tiny star with a huge storm -- just like Jupiter's

While the windy and overcast weather of a stormy day isn't surprising on telluric planets, it's not something most of us readily associate with stars. But it does happen -- the best evidence for this is W1906+40, a distant dwarf star recently described in a study published in the Astrophysical Journal.

NASA reveals Earth-like image of Titan

NASA just released an infrared composite image of Saturn's largest moon, constructed from images taken by the Cassini probe.

Japanese orbiter sends back pictures of Venus

The Japanese Space Agency (JAXA) is probably celebrating right now, as their Akatsuki orbiter reached Venus on December 7. The first time JAXA tried to do this in 2010, they failed because the engine malfunctioned, and the shuttle didn’t enter the Venusian orbit. Aimlessly wandering into space without its main engines, the spacecraft appeared doomed […]

Newly discovered star's chemistry puzzles researchers

A team of Argentinian astronomers, peering up in the night's sky from the Astronomical Observatory of Córdoba has found a new, young lithium-rich giant star that they designated KIC 9821622. And they can't explain where that lithium comes from.

How 2016 Presidential Candidates See Space Exploration

I know you don't like it, but the truth is science is politicized since, ultimately, serious research depends on funding. That doesn't mean, though, that politicians aren't sympathetic or that they do not understand the importance of science. Some seem to do, anyway. But perhaps the most vulnerable area of science to politics, however, is space exploration. Year after year, it seems like NASA's budget keep thinning. Although NASA is still the most resourceful space agency in the world and despite some amazing achievements (Curiosity rover on Mars or New Horizon's flyby past Pluto, just to name a few), things could be a lot better. Arguably, if NASA kept its stellar budget during the Apollo era, we would've likely been on Mars by now, maybe even with a permanent outpost.

Congress passes law that makes extracting resources in space fair game

Officially, US citizens are now entitled to any resources they mine off the moon, asteroid or any celestial body outside Earth.

How the Moon got its tilt

Astronomers describe that the present-day tilt of the Moon is likely a result of collision-free encounters of the early Moon with small planetary bodies.

Blue Origin makes space history: first controlled landing for a rocket

Jeff Bezos just announced a historical feat: Blue Origin, his space company, successfully launched its New Shepard rocket to 329,839 feet — or sub-orbital space — then safely landed the used rocket just a feet away from the launch pad. This is the first time a controlled landing was demonstrated for a rocket, beating Elon Musk's similar efforts to safely land his Falcon 9 rocket. This monumental milestone suggests reusable rockets will shortly become a reality, revolutionizing space flight in the process.

New most distant body in the Solar system identified

A new dwarf planet, designated V774104 has been identified and now takes the crown of most distant object in our solar system, being three times farther away than Pluto. The dwarf planet is estimated to be between 500 and 1000 kilometers across. Astronomers don't yet have enough data to estimate its orbit and estimate that about an year of observations is needed to gather enough data for a precise answer.

What makes a planet? Finally a simple formula that includes exoplanets as well

There is only one clear set of official criteria by which we class or not a cosmic body as a planet. These criteria introduced in 2006 by the International Astronomical Union saw Pluto demoted to the status of dwarf planet. Oddly enough, though, these rules were made for classing planets only in our solar system, meaning the 5,000 exoplanets (what should be planets outside our solar system) identified so far are now in a "definitional limbo," according to planetary astronomer Jean-Luc Margot at UCLA. Luckily, Margot has come up with a solution which seems to work marvelously.

Astronaut food: what astronauts eat in space

ESA and Russia join forces to put man back on the moon

The last time humans set foot on the moon was 1972. Feeling confident it had clearly showed its superiority over Russia, the US felt no more reason to prove itself and immediately shut down subsequent missions. Once with funding gone - and its budget has been thinning since - NASA had to settle for less ambitious goals, and it's not like we can blame them. Building on outpost on the moon, versus say the International Space Station, is not only a lot more expensive, but also impractical. Recent findings, however, suggest there's a lot to gain from having an outpost on the moon, of some sorts at least. That's because the interest has shifted from prestige, or at least not only, to the potentially bountiful economic activities. Minerals, helium-3 (fuel) or precious metals can all be mined from the moon, trillions worth. But before you can shuttle minerals back from the moon, you at least need a footing of some sort. Understanding this, the European Space Agency and Roscosmos banded together to send a robotic probe to an unexplored region of the moon. The ultimate goal, they say, is to prepare the ground for humans.

NASA awards the best designs for a 3-D printed Mars habitat

With today's propulsion tech, it takes at least 1.5 years for a manned crew to reach Mars, and at least as much to get back - provided there's a return mission. There's only so much that can fit in a spacecraft, and besides the supplies astronauts need for the long trip, there's precious cargo that's required to sustain the mission on site like construction materials, lab equipment, food and so on. Remember the last time you went camping? Well, this time we're headed to another planet and forgetting about toiler paper is the least of your worries. But when NASA handles logistics, you know things are tight to the last bolt. Sometimes, outside help and fresh minds are more than welcome, which is why the space agency held a very interesting competition called the 3D-Printed Habitat Challenge Design Competition which awards the most innovative, but practical designs of habitats on Mars.

It's likely not aliens, but it could be - and it's really, really strange.

Earth's gravity pull is opening cracks and faults on the Moon

Just as the Moon is causing waters on Earth to go up and down (tides), so too does the Earth affect the Moon. Recently, researchers have found that our planet's gravitational pull is having a deep effect on our satellite, opening new cracks and faults on its surface.

SpaceX has something major in the works, and we're really excited

Normally, when people say they're working on "the coolest thing ever", we raise our eyebrows in skepticism; but when SpaceX says that... we give them the benefit of a doubt. I mean, they're doing some pretty monumental things as it is, and when they are excited about something, we are excited about something.

When Earth's solid inner core formed: 1 to 1.5 billion years ago

Our planet's magnetic field is the first and ultimate shield that guards life from the elements of space, particularly radiation. It's enough to look at Mars, which also had a magnetic field but only for 500 million years, to see what could happen were it absent: what was once a "blue planet", filled with vasts oceans of liquid water, maybe even vegetation and other life forms, is now a barred red rock. This invisible, protective shield likely existed shortly after the planet formed 4.5 billion years ago, when it was still a big blob of molten rock. It was only after the super hot iron liquid core lost enough heat to freeze (more properly said, it solidified) did the field become strong enough to allow life to foster. Previous studies estimated this happened sometime between 500 million and 2 billion years ago. A more refined analysis by University of Liverpool places the timeline between 1 billion and 1.5 billion years ago.

NASA believes those spots on Ceres are actually salt

A few days ago, we were telling you about some spectacular features on Ceres, the dwarf planet / largest object in the asteroid belt. NASA's astronomers were puzzled by some white patches on Ceres' surface, which they initially presumed to be ice. Now, they believe those patches are actually salt.

How to weigh a star: a new mathematical method

A novel mathematical model can weigh the mass of a pulsar - a rapidly rotating magnetized neutran star - using principles of nuclear physics, rather than gravity. Up until now, the mass of a star could only be determined in relation with other bodies, based on the gravitational pull these exerted. Now, using the new model scientists will be able to study pulsars in isolation, allowing for more precise measurements than ever before.

Pluto's Charon reveals colorful and violent past
