    Japan's rovers send pictures from asteroid

    Japan's space agency (JAXA) has made history by successfully landing two robotic explorers on the surface of an asteroid. The two small "rovers", which were despatched from the Hayabusa-2 spacecraft on Friday, will move around the 1km-wide space rock known as Ryugu. The asteroid's low gravity means they can hop across it, capturing temperatures and images of the surface.

    Preserving dark skies from light pollution so we can still wonder at the stars

    Under a gibbous moon, with the planets Mars and Saturn shining down from a star studded sky, the Killarney Provincial Park Dark Sky Preserve officially opened on Sept. 22 to the delight of a couple of hundred skywatchers. Killarney Park is a beautiful landscape of white hills, deep blue lakes, islands and coastline about three hours north of Toronto on the shores of Georgian Bay. It's been established as a dark sky preserve in part to celebrate 125 years of Ontario Provincial Parks.

    NASA put Kepler back to sleep in hopes it will send data again

    Kepler has been running low on fuel for some time, so much so that NASA even put the spacecraft into a sleep mode in July in order to make sure it had enough fuel to transmit data back to Earth. But the planet-hunter has kept chugging -- it even kicked off a new data collection campaign in August. However, Kepler has run into another snag, and NASA has decided to put it back to sleep for the time being.

    Saturn's rings made of surprising chemical mix

    Political humorist Mark Russel once joked, “The scientific theory I like best is that the rings of Saturn are composed entirely of lost airline luggage.” Well, there’s no luggage, it turns out. But a new study appearing in Science based on data from the final orbits last year of NASA’s Cassini spacecraft shows the rings of Saturn — some of the most visually stupendous objects in the universe — are far more chemically complicated than previously was understood.

    The 8-dimensional space that must be searched for alien life

    A new mathematical model suggests that signs of extraterrestrial intelligence could be common, for all we know—we’ve barely begun investigating the vastness where they might lie. The Fermi paradox is the contrast between the likelihood of life existing elsewhere in the universe and the lack if evidence for it. This is a significant conundrum. On the one hand, there is a strong sense that the conditions on Earth that led to the emergence of life cannot be unique. This makes it seem likely that life must be common.

    Five in a row—the planets align in the night sky

    For the second time this year, the five brightest planets can be seen at the same time. You can catch them by looking towards the western sky after sunset. The planets will form a line rising up from the horizon. Mercury and Venus are low to the west, with bright Jupiter shining just above. Higher up in the northwestern sky is Saturn, and completing the set of five is the red planet Mars, high overhead.

    How did Titan get its haze?

    Titan, Saturn’s largest moon, is enveloped in a thick, hazy atmosphere. One new research collaboration has identified a chemical mechanism that could help to explain how the moon's haze formed. “Both space probes and land-based instruments have identified the chemical composition of the major constituents of the haze,” said Musahid Ahmed, a scientist in Berkeley Lab’s Chemical Sciences Division and co-leader of the study. “However, how some of heavier particles are formed from the lighter gases is still an open question.”

The blast of radiation was more powerful than any such outburst ever detected from the Sun, and would likely affect the habiltability of any planets orbitiing it.

    Mars scientists push NASA to send rock-harvesting rover to two sites

    NASA’s next Mars rover — the first to gather rock samples meant to come back to Earth — should dream big and visit as many places on the red planet as possible, scientists concluded on 18 October. Its stops would probably include some combination of Jezero crater, once home to river deltas and a lake; Northeast Syrtis, which contains some of the most ancient rocks on Mars; and Midway, a compromise option located between those two. Project scientists have proposed visiting both Jezero...

    Halo of the Cat's Eye

    Not a Falcon 9 rocket launch after sunset, the Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its haunting symmetries are seen in the very central region of this composited picture, processed to reveal an enormous but extremely faint halo of gaseous material, over three light-years across. Made with data from ground- and space-based telescopes it shows the extended emission which surrounds the brighter, familiar planetary nebula. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. But only more recently have some planetaries been found to have halos like this one.

    This weekend, go outside and look up in the dark hours before dawn to witness the annual Orionid meteor shower, which will hit its peak overnight on October 21-22. You may have seen a few stray meteors zooming across the sky, leftover Draconids whose peak passed earlier this month or leftover meteors from the South Taurid shower that’s still ongoing. But this week, and more specifically this weekend, the Orionid meteors will be easy to spot.

    NASA to soon end active efforts to restore contact with Opportunity

    NASA expects to soon end efforts to contact the Opportunity Mars rover, silent for more than four months after a major dust storm, but will continue to listen for signals from the spacecraft for months to come. Opportunity, which has been on Mars since January 2004, last contacted Earth June 10. A powerful globe-spanning dust storm blocked the sun and deprived the rover of solar power, putting it into a low-power mode.

When he was old enough to say what he wanted to be when he was older, his answer was always immediate: An astronaut. Like many with such aspirations, Shirshekar dreamed of a future working at NASA or a private U.S. space company. It was the gold standard, he thought, something to strive for.

At the southern pole, most of the ice is concentrated at lunar craters, while the northern pole's ice is more widely, but sparsely spread.

    Morning, Kepler! NASA's Planet-Hunting Spacecraft Wakes Up Again

    The Kepler roller-coaster ride continues. NASA's low-on-fuel Kepler space telescope, which has discovered more than 2,650 alien planets to date, has awoken from yet another slumber and begun making science observations again, agency officials announced today (Sept. 5). The $600 million Kepler mission launched in March 2009, tasked with determining how common Earth-like planets are around the galaxy. The spacecraft initially studied more than 150,000 stars simultaneously, looking for tiny brightness dips caused by the passage of orbiting planets across these stars' faces.

The passenger will fly on the monster ship around the Moon, though there are no details yet regarding when the trip will happen. SpaceX says it will announce who is flying — and why — on Monday, September 17th. The BFR, or the Big Falcon Rocket, is the giant rocket that SpaceX is currently developing to send humans to the Moon and Mars. The BFR design, presentated by CEO Elon Musk last year, consists of a combined rocket and spaceship, called the BFS for Big Falcon Spaceship.

    Space observatory at centre of alien conspiracy asks for ‘patience’

The Sunspot Solar Observatory in Sunspot, New Mexico caught the attention of the world when it was shut down by FBI agents who reportedly swooped on the facility after arriving in elite Blackhawk helicopters. It led immediately to suggestions the advanced technology inside of the facility spotted something it shouldn’t – such as proof of extraterrestrials, UFOs or even some baseless speculation that the observatory had spotted that the sun has started dying.

    A Solar Filament Erupts

    What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere.
