Inside Solar System's Biggest Moon: an Ocean

Jupiter's Ganymede may hold more water than Earth

(Newser) - Where there is water, there could be life, NASA scientists say—and they have found evidence of a vast amount of water on Ganymede, Jupiter's biggest moon and the biggest moon in the solar system. Ganymede is the only one known to have its own magnetic field, and Hubble...

Jupiter's Red Spot Isn't What We Thought It Was

Researchers re-create phenomenon in lab

(Newser) - Scientists have made their own version of Jupiter's Great Red Spot in a lab, and it suggests that the spot's cause is very different from what's been postulated. An existing theory holds that the spot is the result of chemicals underneath the planet's clouds. But following...

Jupiter's Great Red Spot Has Really Shrunk

It looks more like a circle than an oval

(Newser) - The signature red spot we see in pictures of Jupiter could fit three Earths next to each other—in the late 1800s. The Great Red Spot is getting smaller, and the reason is a mystery, Reuters reports. It was some 25,000 miles across in the late 19th century; by...

Jupiter Forecast: Rain, With Chance of Diamonds

Two scientists float the possibility of liquid gems in space

(Newser) - It's just a theory, but a pretty dazzling one. Two scientists this week laid out the tantalizing possibility that Jupiter sees raindrops of liquid diamond and Saturn gets diamond hail, reports Nature . If true, both planets would be teeming with the gems. "If you had a robot there,...

Search Begins for Life in Antarctic Lake

Lake Ellsworth has been isolated for up to 500K years

(Newser) - What lurks in the pitch black, near-freezing waters of Lake Ellsworth? That's what British researchers, who began their trek to the lake in October 2011, hope to find out in as soon as a week. They've begun drilling through more than two miles of ice to reach the...

Jupiter Takes New Hit for the Team

Flash believed to be collision with asteroid or comet

(Newser) - For the third time in four years, Jupiter appears to have been hit by something big enough to have done a lot of damage to our planet or any other unlucky enough to be in its way. A flash on Jupiter captured by amateur astronomers is believed to have been...

European Mission: Can Life Exist on Jupiter's Moons?

JUICE probe will launch in 2022

(Newser) - The first Europe-led mission to the outer solar system will explore the icy moons of Jupiter. The European Space Agency approved the JUICE—JUpiter ICy moons Explorer—mission yesterday. The project's solar-powered spacecraft is scheduled to launch in 2022 and arrive in the Jovian system by 2030 to spend...

Venus, Jupiter Nestle Nice and Close Tonight

Planets will dazzle skywatchers with annual get-together

(Newser) - Look out the window tonight and you'll see two planetary pals coming together for their annual rendezvous. Venus and Jupiter, which have been approaching each other for months, will finally dazzle skywatchers this week by nestling nice and close—from our perspective, in fact, just a few inches apart....

Oxygen Flows on Saturn's Icy Moon

Dione can't support life or liquid oceans, but check out other gas giant moons

(Newser) - Good news for future space colonists: Saturn's icy moon, Dione, contains a thin layer of oxygen that hints at life on other gas giant satellites, the BBC reports. Spotted by the Cassini spacecraft about two years ago, Dione's oxygen layer lacks the necessary density to support life and...

Venus, Jupiter, Moon Come Together This Weekend

Stargazers will be able to see convergence around the world

(Newser) - Venus, Jupiter, and Earth's moon are coming together Saturday and Sunday to put on a brilliant show in the night sky, the AP reports. Venus and Jupiter have already been lining up, and a crescent moon will join them this weekend; stargazers will be able to see the convergence...

Is Jupiter's Core Dissolving?

Theory holds that midsection is slowly shrinking

(Newser) - Jupiter may be the largest planet in our solar system, but what if its massive core is actually dissolving? Jupiter's core of iron, rock, and ice is suspended in a sea of hydrogen and helium, under pressure 40 million times greater than that which we experience on Earth, and...

Jupiter Moon Lakes Might Support Life

Vast lakes lie just beneath Europa's icy surface: Scientists

(Newser) - The chances of life existing on Jupiter's ice-covered moon Europa—and of Earthlings being able to find it—are looking a lot stronger, NASA scientists say. A vast ocean is believed to lie beneath as much as 20 miles of ice on Europa, but new research suggests that huge...

Jumping Jupiter! 5th Giant Planet Evicted Eons Ago

Theory says it got knocked out of our early solar system

(Newser) - Our young solar system may have had another huge planet that got knocked into deep space by Jupiter, reports Wired . Astronomers at the Southwest Research Institute in Texas arrived at this "Jumping Jupiter" theory because computer simulations can't figure out how our modern solar system emerged as is...

Solar System Kicked Out Extra Planet

Early ejection may have helped Earth survive

(Newser) - Thank your lucky stars that our solar system was only big enough for eight planets. Apparently a ninth one—and a gas giant, no less—was nudged out billions of years ago and made room for Earth to survive. In computer simulations of our solar system's evolution, Colorado scientist...

NASA Probe to Blast Off, Destination: Jupiter

Juno to explore origins of the solar system; liftoff scheduled for 11:34am ET

(Newser) - Today NASA will launch a spacecraft that they're hoping will pry the secrets of the solar system from Jupiter. Dubbed "Juno" (Jupiter’s wife in Roman mythology, get it?), the probe will take five years to travel to Jupiter, arriving on July 4, 2016, the New York Times...

Four Planets Align This Month

Mercury, Venus, Mars, and Jupiter in rare convergences

(Newser) - This month, Mercury, Venus, Mars, and Jupiter will take part in a series of what Space.com calls "celestial summit meetings." The four planets will converge twice to form a "trio," defined as an instance when three planets fit in a circle with a minimum 5-degree...

New Planet Expected to Crash and Burn

It defies laws of physics

(Newser) - Scientists in the UK have discovered a planet that defies the laws of physics, the Independent reports. WASP-18b, which is orbiting a star 1,000 light years from Earth, is so big and close to the sun that it should be pulled toward it. "The spin of the star...

Hubble Snaps Photos of Jupiter Impact

(Newser) - NASA pulled the recently upgraded Hubble space telescope out of testing yesterday to take a photo of the Earth-sized impact scar on Jupiter, CNN reports. “Because we believe this magnitude of impact is rare, we are very fortunate to see it with Hubble,” a NASA scientist says. “...

Jupiter Slammed by Mystery Object

(Newser) - A massive mysterious object scientists believe may be a comet slammed into Jupiter yesterday, AP reports. The Earth-size impact "scar" left by the object was caught on NASA's powerful infrared telescope in Hawaii. The agency was alerted to the new mark on the planet by an amateur astronomer in...

NASA Plans Jupiter Mission

(Newser) - NASA plans to send an orbiter to study the mysteries of one of Jupiter's moons, the Washington Post reports. Scientists suspect Europa has a massive ocean—possibly bigger than all of the Earth's oceans combined—beneath its ice-covered surface, the Post notes. Don't look up just yet: The $3 billion...
