Horizon, 1997-1998, Mir Mortals. Welcome to your planet - Planet Labs. DigitalGlobe. Kepler Space Telescope. Breakthrough Starshot. The story of humanity is a story of great leaps – out of Africa, across oceans, to the skies and into space.
Since Apollo 11’s ‘moonshot’, we have been sending our machines ahead of us – to planets, comets, even interstellar space. But with current rocket propulsion technology, it would take tens or hundreds of millennia to reach our neighboring star system, Alpha Centauri. The stars, it seems, have set strict bounds on human destiny. Until now. In the last decade and a half, rapid technological advances have opened up the possibility of light-powered space travel at a significant fraction of light speed.
Breakthrough Starshot aims to demonstrate proof of concept for ultra-fast light-driven nanocrafts, and lay the foundations for a first launch to Alpha Centauri within the next generation. A number of hard engineering challenges remain to be solved before these missions can become a reality. Titan Submarine: Exploring the Depths of Kraken.

Ask a satellite floating 400 miles overhead. Powerful space cameras and infrared imagery can now pinpoint and record structures less than two feet wide and completely invisible to the naked eye. James Webb Space Telescope (JWST) NASA. IAU Minor Planet Center. Helicopters on Mars? Why Not? Helicopters on Mars?
Why Not? 3-D Exploration! Researchers want a vehicle that can cover ground quickly but also move slowly to examine an area. They want a vehicle that can "see" large areas from a height, but get down to the ground when they find something interesting. A rover can't do this because it can't fly. Despite Mars having a thin, cold, carbon-dioxide atmosphere operating a rotorcraft is entirely possible -- the low gravity helps somewhat, but the real secret is ultra-lightweight hardware components. NASA has been investigating and developing unmanned helicopters to land on and to assist in the exploration of Mars. One project investigates putting autorotating rotors on capsule-type reentry vehicles. Another project is examining the flight of birds and insects for possible ideas to apply to unmanned helicopters which would be used to explore Mars ' surface.
Did You Know? That helicopters are safer than airplanes. Possible Careers Working with Rotorcraft Reducing Noise. Planet Four. Event Horizon Telescope. Science. The Moon Ignoring the occasional pre-telescopic appearance of exceptionally large sunspots, the Moon is the only heavenly body which shows features to the naked eye--the Man in the Moon.
These features are permanent, and it was therefore obvious that the Moon always keeps its same face turned to us (although there are minor perturbations that were not noticed until later). But it's not for drinking, scientists say. It’s one of the most intriguing questions in science: Could life exist on Mars today?
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. The flower you see in this animation isn’t NASA’s attempt to celebrate the coming of spring.
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. Thoth Technology's Brendan Quine, who invented the prototype, explained: "Astronauts would ascend to 12 miles by electrical elevator. From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refuelling and reflight. " The concept of space elevators has been around for a long time, largely as a potential alternative to highly inefficient, fuel-guzzling rockets. 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.
This video is a striking reminder that even though we grow up looking at diagrams of the solar system with the planets neatly packed together, it's actually almost entirely made up of empty space. The distance between our planet and the others is many times larger than we can wrap our heads around — and the planets themselves are small enough to fit in the gap between Earth and the moon. (CapnTrip) Wow! signal. The Wow!
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. The signal bore the expected hallmarks of non-terrestrial and non-Solar System origin.
It lasted for the full 72-second window that Big Ear was able to observe it, but has not been detected again. The signal has been the subject of significant media attention.

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. 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.
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.
