Earth Could Face A Grave Asteroid Threat This Autumn. Aside from all the neato deep space exploration NASA conducts, one of the space agency’s responsibilities includes keeping track of all the potentially dangerous objects hurtling around our own neck of the space woods.
NASA tracks over 15,000 so-called near-Earth objects (NEOs), many of which have been passing uncomfortably close to Earth lately. The threat of these NEOs is so great that NASA and FEMA have recently teamed up for asteroid strike preparedness drills and the White House itself drafted its first “National Near-Earth Object Preparedness Strategy” earlier this year. Worried yet? Keep reading. We’re surrounded. A year of earth in the #solarsystem.
A group of Soviet cosmonauts singing along to popular Soviet song "May There Always Be Sunshine", 1963. Scientists have proved you can hear the 'chirp' of gravity. Researchers have announced the third detection of gravitational waves—ripples in the fabric of space and time.
Albert Einstein predicted gravitational waves as part of his theory of general relativity more than 100 years ago, but it has taken astrophysicists more than 50 years of trial and error to find the direct evidence to support his theory. The Laser Interferometer Gravitational-wave Observatory (LIGO) made the detection January 4, 2017. Gravitational waves pass through Earth and the extremely sensitive LIGO detectors can “hear” them.

Today’s spacesuits are designed to work well while astronauts float around outside the International Space Station.
But they’re not quite right for walking around on the moon or Mars—they’re too heavy and don’t provide enough flexibility in the hips and knees. That’s why NASA is investing in a next-generation spacesuit for exploring deep space. However, the space agency may soon find itself up s*** creek without a pressure suit.

*****Enceladus discoveries Apr 2017. Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other "ocean worlds" in our solar system and beyond.
The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope. In the papers, Cassini scientists announce that a form of chemical energy that life can feed on appears to exist on Saturn's moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter's moon Europa. This is the closest we've come, so far, to identifying a place with some of the ingredients needed for a habitable environment. At Saturn, Energy for Life. *****Enceladus: Life on another planet? Ever since studies started suggesting that chemical reactions between water and rock on Saturn’s moon Enceladus could provide enough energy in the water to feed microbial life, scientists have been searching for proof that the right sort of reactions really do occur.
And during its last dive through the icy plumes that Enceladus erupts into space in October 2015, the Cassini spacecraft has finally managed to find it – in the form of molecular hydrogen. The finding, published in Science, means the moon can now be considered highly likely to be suitable to host microbial life. OS OpenData Easter 'Egg's.

This is how Jupiter 'shepherds' the asteroid belt, preventing asteroids from falling into the sun or hitting planets. If Betelgeuse would explode transiting from the red super giant stage to supernova then our sky would light continuously for two months.
Something a bit different - the newly discovered ~5-meter asteroid (meteoroid), 2017 GM, will just miss the Earth today at only 15 000 km. Since the sun is also moving, this is a better representation of how the planets revolve around the sun. Unveils New Searchable Video, Audio and Imagery Library. We are so insignificant in the universe. *****Meteor showers from space. What am I looking at?
Meteor showers on Earth are caused by streams of meteoroids hitting our atmosphere. These meteoroids are sand- and pebble-sized bits of rock that were once released from their parent comet. Some comets are no longer active and are now called asteroids. Lovely shot David. Sand dunes are scattered across Mars and one of the larger populations exists in the Southern hemisphere. 23 March 1840.

Kornmesser An artist’s impression of Proxima b is beautiful — and a fantasy. In a generation or two, a mission to the planet could yield a more accurate representation. Anybody who longs to see an alien world up close got an exciting gift last year. In August, researchers reported the discovery of a potentially habitable, Earth-sized planet orbiting the Sun’s closest stellar neighbour — Proxima Centauri, a mere 1.3 parsecs, or 4.22 light years, away.
It’s a tempting — some might say irresistible — destination. The idea of reaching Proxima b is not just science fiction. Getting there won’t be easy. Other groups are also aiming for nearby stars, but none has the momentum — or money — of Breakthrough Starshot. These seven alien worlds could help explain how planets form. NASA/ESA/STScI/J. de Wit An artist's illustration shows two Earth-sized planets spinning across the face of an M dwarf star called TRAPPIST-1.
Seven alien, Earth-sized worlds bask in the cool, red light of their parent star. The planetary menagerie exists around a star overlooked by other exoplanet hunters, although it is just 12 parsecs (39 light years) from Earth. Astronomers have found other seven-planet systems before, but this is the first to have so many Earth-sized worlds. #OTD 1971: Paul Trevillion is a multi-talented man; artist, author, speed-kissing world champ... but could he teach Patrick Moore to putt? Apollo 16 astronaut Charles Duke immortalizes his family by leaving a photo of them on the moon in 1972. Where will space technology take us by 2030, and what does this mean for life on Earth? Space technologies will one day take us to asteroids, Mars and back to the moon, and the impact of these missions will be felt back on Earth, says George Whitesides, Chief Executive Officer at Virgin Galactic and co-chair of the Global Future Council on Space Technologies. In this interview, he explains how the latest developments in space technologies will help bring about revolutions in wifi access, travel and beyond.
What is the state of space technology today? We are at an exciting moment. What we see are several converging trends that will change how we approach space technologies, at a rate of innovation that we haven’t seen in a long time. The power of miniaturization, for example, is having a huge impact on satellites. The exploration of space is also becoming global.
What excites me most about space technologies is that it's an opportunity for us to put the best of humanity forward into the future. “Are We Alone in the Universe?” Winston Churchill's Lost Extraterrestrial Essay Says No. Winston Churchill, British prime minister and one of history’s most influential statesmen, was undoubtedly a man with weighty questions on his mind. How best to save the British Empire? He must have mused. What will the postwar world look like? He surely wondered.
