The Drake Equation

" How can we estimate the number of technological civilizations that might exist among the stars? While working as a radio astronomer at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived an approach to bound the terms involved in estimating the number of technological civilizations that may exist in our galaxy. The Drake Equation, as it has become known, was first presented by Drake in 1961 and identifies specific factors thought to play a role in the development of such civilizations. Although there is no unique solution to this equation, it is a generally accepted tool used by the scientific community to examine these factors.-- Frank Drake, 1961.

Astronomers are exploring what might be described as the first astronomical observing tool, potentially used by prehistoric humans 6,000 years ago.

They suggest that the long, narrow entrance passages to ancient stone, or 'megalithic', tombs may have enhanced what early human cultures could see in the night sky, an effect that could have been interpreted as the ancestors granting special power to the initiated. The team present their study at the National Astronomy Meeting, being held this week in Nottingham. The team's idea is to investigate how a simple aperture, for example an opening or doorway, affects the observation of slightly fainter stars. They focus this study on passage graves, which are a type of megalithic tomb composed of a chamber of large interlocking stones and a long narrow entrance.

Breakthrough Starshot

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. Titan Submarine: Exploring the Depths of Kraken.

Helicopters on Mars? Why Not?

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. Planet Four. 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?

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.

Researchers haven't spied the water directly. Ashwin Vasavada, project scientist for the Mars rover Curiosity at NASA’s Jet Propulsion Laboratory, called the discovery exciting but not surprising.

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. 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) What's more, the distance to any other star is many times greater still.

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.[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. The signal has been the subject of significant media attention. Interpretation of the paper chart[edit] Biosphere 2. Black hole glimpsed playing cosmic billiards - BBC News. 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.

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. 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. Moons of Jupiter.
