But it's not for drinking, scientists say. It’s one of the most intriguing questions in science: Could life exist on Mars today?

but it's not for drinking, scientists say

On Monday came an answer: Yes, quite possibly. Scientists using observations from NASA’s Mars Reconnaissance Orbiter said they’ve found powerful evidence that briny water routinely flows on the Martian surface. This particular water source is so salty that it would probably be too harsh for life as we know it, scientists said. But the revelation, described in the journal Nature Geoscience, strengthens the potential for life on our rust-hued neighbor — not just during its wetter past but also its arid present, experts said. “It suggests that it would be possible for there to be life today on Mars,” said John Grunsfeld, associate administrator of NASA's Science Mission Directorate in Washington.

PlanetQuest - The Search for Another Earth

It’s actually the latest design in a cutting-edge effort to take pictures of planets orbiting stars far from the sun. Astronomers have been indirectly detecting exoplanets for more than 15 years, but actually taking a picture of one has proven an immensely difficult task. Picking out the dim light of a planet from a star billions of times brighter is akin to finding a needle in a cosmic haystack, especially when the planet in question is a small, rocky world similar to Earth. In order to achieve this feat, researchers are developing techniques to block out the starlight while preserving the light emitted by the planet.

This is called starlight suppression. A Year Of Sunrises. Inflatable, 20km tall 'space elevator' could replace rockets. A Canada-based space company has patented an inflatable "space elevator" designed to propel astronauts up into the stratosphere before they blast off into space.

If the maverick "ThothX Tower" were ever actually built, it would soar 20km (12.4 miles) into the sky, and would reduce the cost of space launches by 30 percent in fuel costs alone, according to estimations. It's even hoped that the lift could replace some kinds of satellites. Insight: Introduction. This mesmerizing video shows how incredibly vast space really is. Light travels at about 186,000 miles per second.

That's an incomprehensibly fast speed — faster than any other object in the universe. But the video above shows how huge just our corner of the galaxy is, even for a photon of light traveling at that remarkable speed. The film, by artist Alphonse Swinehart, gives you the view you'd see if you were a particle of light traveling from the sun across the solar system — even though it's 45 minutes long, you still don't even reach Saturn. Wow! signal. The Wow!

Wow! signal

Signal was a strong narrowband radio signal detected by Jerry R. Ehman on August 15, 1977, while he was working on a SETI project at the Big Ear radio telescope of Ohio State University, then located at Ohio Wesleyan University's Perkins Observatory in Delaware, Ohio.[1] The signal bore the expected hallmarks of non-terrestrial and non-Solar System origin[citation needed]. It lasted for the full 72-second window that Big Ear was able to observe it, but has not been detected again. HI-SEAS. Venera-9 and 10. In 1975, Soviet scientists launched two probes to Venus, which transmitted first ever images from the surface of the planet.

Astronomers have witnessed two big blobs of plasma, shot into space by a black hole, cannoning into each other in a dramatic cosmic billiard-shot.

Black hole glimpsed playing cosmic billiards - BBC News

The supermassive black hole sits at the heart of the sixth brightest galaxy in our sky, blasting out a jet of plasma at 98% of the speed of light. A fast-moving knot within that jet bore down on another, in a dazzling impact. It was captured in a series of images snapped by the Hubble Space Telescope, spanning 20 years. 6-billion-year-old quasar spinning nearly as fast as physically possible. Supermassive black holes are powerful engines, pumping matter and energy into their environments.

Despite their size and influence, they are also relatively small, making detailed observations a major challenge. For that reason, most of the data we have on them involves tracking the matter swirling around the black hole rather than the properties of the black hole itself. Astronomers have now used gravitational magnification to measure the rotation rate of a supermassive black hole in a very distant galaxy.

From four separate images of the same black hole, R.C. Reis, M.T. Moons of Jupiter. A montage of Jupiter and its four largest moons (distance and sizes not to scale) Eight of Jupiter's moons are regular satellites, with prograde and nearly circular orbits that are not greatly inclined with respect to Jupiter's equatorial plane.

Moons of Jupiter

The Galilean satellites are ellipsoidal in shape, due to having planetary mass, and so would be considered dwarf planets if they were in direct orbit about the Sun. The other four regular satellites are much smaller and closer to Jupiter; these serve as sources of the dust that makes up Jupiter's rings.The remainder of Jupiter's moons are irregular satellites, whose prograde and retrograde orbits are much farther from Jupiter and have high inclinations and eccentricities. These moons were probably captured by Jupiter from solar orbits. There are 16 recently discovered irregular satellites that have not yet been named. Characteristics[edit] Origin and evolution[edit] Astrophotography. Space Shuttle. Shuttle Carrier Aircraft and space shuttle mockup to become centerpiece of new exhibit at Space Center Houston visitor center near NASA's Johnson Space Center. Still in its protective shrink wrap, space shuttle Atlantis has been raised and tilted into display position at the Kennedy Space Center Visitor Complex.

Atlantis starred in a daylong parade and celebration as the shuttle was moved into an exhibit hall at the Kennedy Space Center Visitor Complex. The storied spacecraft's pair of 60-foot-long doors were closed Sept. 20 during preps for permanent display. NASA's Shuttle Carrier Aircraft pilots will carry Endeavour to its new home in Los Angeles. Moon Base Possible through Lava Tubes. Scientists and theorists had come up with many ideas to open up a functional base on the moon but the issue of radiation outweighs the possibilities. Scientists have recently discovered lava tubes where a base could be safely constructed.

In volcanic tubes are now considered to be safe and ideal sites for settling in. Scientists are accessing the situation and are trying to figure out that how stable these tubes are, they are studying the features and they have discovered that the tubes which are at least 1 km in size could be ideal for human settlement. Open Space Agency. Why are there dozens of dead animals floating in space? On July 20, 1969, Neil Armstrong became the first man in history to step on the surface of the moon. Millions of people tuned in to a broadcast of the event, and after Edwin "Buzz" Aldrin Jr. joined Armstrong, the two spent about two and a half hours gathering lunar rocks to bring back for analysis.
