Billions of years ago when the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water – a critical ingredient for life. The animation shows how the surface of Mars might have appeared during this
Comet Encke will fly by Mercury within 0.025 AU (3.74 million km) on November 18, 2013 and only a day later, Comet ISON will pass it at 0.24 AU. This is a unique cosmic coincidence and NASA's MESSENGER spacecraft, which is orbiting the planet,
Observers around the world are reporting that Comet ISON brightened sharply last night and is now at the threshold of naked-eye visibility. By some reports, ISON surged in brightness by approximately 2 magnitudes over last 24 hours and is now brighter than
Comet ISON is every day more and more closer to the Sun, and with every new day it reveals more new details. More astronomers report clearly visible double tail feature. Primary ion gas tail developed a dust tail companion so now Comet ISON is double tail
ESA’s GOCE, 1100 kg heavy, satellite has re-entered Earth’s atmosphere. The spacecraft fell at approximately 00:16 UTC on November 11, 2013 over the South Atlantic Ocean east of Tierra del Fuego, off the southernmost tip of the South
Comet ISON has almost completed its journey from the Oort Cloud to Sun's photosphere and is now inside the orbit of Earth. On November 28, 2013 Comet ISON will fly only 1 million kilometers (2.7 solar radii) above Sun's surface,
After nearly tripling its planned lifetime, the ESA's Gravity field and steady-state Ocean Circulation Explorer – GOCE – has completed its mission. The satellite will re-enter our atmosphere this weekend and break-up into pieces. It is
Astronomers have observed a unique and baffling object in asteroid belt with six comet like tails of dust radiating from it. While this object is on an asteroid-like orbit, it looks like a comet, and is sending out tails of dust into space.
Unlike all other
When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live,
On this day, exactly 10 years ago, the largest ever recorded solar flare in history erupted from Sun's western limb. This mega flare started its historic eruption at 19:29 UTC from Active Region 10486 and peaked around 19:50 UTC.
Ionizing radiation from the
