New Model Predicts That We’re Probably the Only Advanced Civilization in the Observable Universe

/0 Comments/in , /by

The Fermi Paradox remains a stumbling block when it comes to the search for extra-terrestrial intelligence (SETI). Named in honor of the famed physicist Enrico Fermi who first proposed it, this paradox addresses the apparent disparity between the expected probability that intelligent life is plentiful in the universe, and the apparent lack of evidence of extra-terrestrial intelligence (ETI).

In the decades since Enrico Fermi first posed the question that encapsulates this paradox (“Where is everybody?”), scientists have attempted to explain this disparity one way or another. But in a new study conducted by three famed scholars from the Future of Humanity Institute (FHI) at Oxford University, the paradox is reevaluated in such a way that it makes it seem likely that humanity is alone in the observable universe.

The study, titled “Dissolving the Fermi Paradox”, recently appeared online. The study was jointly-conducted by Anders Sanberg, a Research Fellow at the Future of Humanity Institute and a Martin Senior Fellow at Oxford University; Eric Drexler, the famed engineer who popularized the concept of nanotechnology; and Tod Ord, the famous Australian moral philosopher at Oxford University.

For the sake of their study, the team took a fresh look at the Drake Equation, the famous equation proposed by astronomer Dr. Frank Drake in the 1960s. Based on hypothetical values for a number of factors, this equation has traditionally been used to demonstrate that – even if the amount of life developing at any given site is small – the sheer multitude of possible sites should yield a large number of potentially observable civilizations.

This equation states that the number of civilizations (N) in our galaxy that we might able to communicate can be determined by multiplying the average rate of star formation in our galaxy (R*), the fraction of those stars which have planets (fp), the number of planets that can actually support life (ne), the number of planets that will develop life (fl), the number of planets that will develop intelligent life (fi), the number civilizations that would develop transmission technologies (fc), and the length of time that these civilizations would have to transmit their signals into space (L).

Mystery Radio Bursts From Space Just Got Even Weirder

/0 Comments/in , /by

There’s a new twist in the tale of one of the strangest objects in the sky.

About three billion light-years away, that mysterious object continually hurls humongous blasts of radio waves into the cosmos. Now, scientists have spied in those waves the spiraling signature of an extremely strong magnetic field, suggesting that the cosmic oddity exists in an intense galactic environment containing a powerfully magnetic source.

The discovery adds to astronomers’ understanding of phenomena known as fast radio bursts, or FRBs, which are magnificently energetic flashes of radio waves that last for mere fractions of a second. It also allows researchers to paint a clearer picture of what conditions are like in an incredibly distant corner of the universe.

“We’re directly probing the local environment of a source in a galaxy billions of light-years away,” says Emily Petroff of ASTRON, the Netherlands Institute for Radio Astronomy. “It’s like the power to zoom in at a billion times magnification on an extreme object somewhere else in the universe.”

While the exact source of the magnetism is unclear, it’s possible this FRB is next to a supermassive black hole, like the churning bruiser near our galaxy’s center, or swaddled in the chaotic aftermath of a stellar explosion.

3 New Earth-Sized Planets May Have Signs of Life

/1 Comment/in , /by

A Belgian-led team reported Monday that it’s discovered three Earth-sized planets orbiting an ultra-cool dwarf star less than 40 light-years away. It’s the first time planets have been found around this type of star — and it opens up new, rich territory in the search for extraterrestrial life.

Because this star is so close and so faint, astronomers can study the atmospheres of these three temperate exoplanets and, eventually, hunt for signs of possible life. They’re already making atmospheric observations, in fact, using NASA’s Spitzer Space Telescope. The Hubble Space Telescope will join in next week.

Altogether, it’s a “winning combination” for seeking chemical traces of life outside our solar system, said Massachusetts Institute of Technology researcher Julien de Wit, a co-author of the study, released by the journal Nature.

A Peek Inside the Orion Spacecraft That Will Fly Us to Mars

/1 Comment/in , /by

The length of humanity’s planned journey to Mars will be much more than the 6 months or so that it’ll take to fly there. Though NASA plans to send astronauts to the red planet sometime in the 2030s or 40s, it’s going to take decades of research and testing to develop the equipment to get us there.

The ship that will carry humans to another planet is the Orion capsule, of which NASA is already testing prototypes. And at the Johnson Space Center in Houston, Popular Science got to take a look inside an Orion mock-up.

If the spacecraft looks a little cramped for a 6- to 9-month trip, that’s because the capsule won’t be going to Mars alone. The plan is to launch Orion from Earth and, once in space, have it dock with a larger habitat module (whose design is still TBD) before beginning its journey to Mars.

Plus, Orion engineer Stuart McClung says the spacecraft is not all that small compared to what we use to send astronauts to the International Space Station. “If you walk over to the Soyuz capsule on the other side of the building, this is like a big stretch limo compared to that Soyuz capsule.”

The engineers at the Johnson Space Center use the Orion mock-up for designing, training, and testing–for example, deciding on a seat layout and crew interfaces. (Read more from “A Peek Inside the Orion Spacecraft That Will Fly Us to Mars” HERE)

The Mystery Behind the Air Force’s Classified Space Plane

/0 Comments/in , /by

The last time the Air Force’s super secretive X-37B space plane launched, it didn’t come down until almost two years later–674 days to be exact. On Wednesday, it launched again, and was scheduled to stay in orbit for 270 days. Or maybe more.

No one knows for sure because the largely classified project is shrouded in mystery. The Air Force will only say that it will test a new, experimental thruster. The rocket carrying the space craft will also deliver a small satellite that would fly using a “solar sail.” But the broader mission of the Boeing-made X-37B, which looks like a miniature version of a the space shuttle, is not publicly known.

Space has become an increasingly important part of national security, a realm the Pentagon and the intelligence community is keenly focused on. And the ability to keep an unmanned space craft that could circle the Earth for months at a time and then land on an airstrip so that it could be used again could have all kinds of potential, from keeping an eye on the weather as well as the enemy.

“Space is so vitally important to everything we do,” Maj. Gen. Tom Masiello, the commander of the Air Force Research Laboratory, Space and Missile Systems Center, said in a recent statement. “Secure comms, ISR [intelligence, surveillance and reconnaissance], missile warning, weather prediction, precision navigation and timing all rely on it, and the domain is increasingly contested.”

In Congressional testimony last month, Air Force Lt. Gen John Raymond said that space has become a “warfighting domain,” and he warned that other countries, particularly, China and Russia, “remain concerns for us as we assess threats in the space domain.” Officials have said the countries have the ability to blind satellites with lasers or blow them up with missiles.

Mysterious X-37B Military Space Plane to Fly Again Next Month

/1 Comment/in , /by

x37b-space-plane-in-orbitThe United States Air Force’s X-37B space plane will launch on its fourth mystery mission next month.

The unmanned X-37B space plane, which looks like a miniature version of NASA’s now-retired space shuttle orbiter, is scheduled to blast off atop a United Launch Alliance Atlas V rocket from Florida’s Cape Canaveral Air Force Station on May 20.

“We are excited about our fourth X-37B mission,” Randy Walden, director of the Air Force Rapid Capabilities Office, said in a statement. “With the demonstrated success of the first three missions, we’re able to shift our focus from initial checkouts of the vehicle to testing of experimental payloads.”

The X-37B’s payloads and specific activities are classified, so it’s unclear exactly what the spacecraft does while zipping around the Earth. But Air Force officials have revealed a few clues about the upcoming mission.

“The Air Force Research Laboratory (AFRL), Space and Missile SystemsCenter (SMC) and the Air Force Rapid Capabilities Office (AFRCO) are investigating an experimental propulsion system on the X-37B on Mission 4,” Capt. Chris Hoyler, an Air Force spokesman, told Space.com via email. (Read more from “Mysterious X-37B Military Space Plane to Fly Again Next Month” HERE)

European Satellites Launched to Eye Earth’s Magnetic Field

/2 Comments/in , /by

Photo Credit: Reuters The European Space Agency on Friday launched three satellites it hopes will help understand why the magnetic field that makes human life possible on Earth appears to be weakening.

The satellites, comprising ESA’s Swarm project, were launched from Russia’s Plesetsk Cosmodrome on a Rockot vehicle at 7.02 a.m. EST and were placed in near-polar orbit at an altitude of 490 kilometers (304 miles) about 91 minutes later.

Data that Swarm is due to collect for the next four years will help improve scientists’ relatively blurry understanding of the magnetic field that shields life on Earth from deadly solar radiation and helps some animals migrate.

Scientists say the magnetosphere is weakening and could all but disappear in as little as 500 years as a precursor to flipping upside down.

Cassini Takes First-Ever Pictures of Earth from Spacecraft Orbiting Saturn

/1 Comment/in , /by

Thousands of astronomy fans looked to the heavens and posed for a unique picture on Friday afternoon – a shot of planet Earth from Saturn.

The first photos are are just being transmitted back now – but anyone who participated in the ‘Day the Earth Smiled’ shouldn’t hope to see their face. This was, after all, a 898million-mile photo op.


The photos, some of which have been enhanced by astronomers, show Earth as a tiny dot – only a little bigger than the North Star appears in our sky – illuminating the skies beyond Saturn.

The images were taken by the Cassini spacecraft, which has been orbiting the ringed giant since its arrival in the Saturn system in 2004.


The Earth has only been pictured in images from outer space on two other occasions. The first was in 1990, when Voyager 1 captured an image from 3.7 billion miles away. The second occasion was when Cassini took a photo in 2006 from 926 million miles away.

Alaska May Events from Space

/0 Comments/in , /by

Following an April which was the coldest on record in many locations (including Fairbanks), May was a month with more record events. Anchorage saw it’s second latest measurable snowfall on May 18th which made the 2012-2013 snow season on record. The record cold also delayed the river breakup, which set the stage for the severe ice jam flooding in Circle and Galena.

The MODIS instrument on NASA’s Terra satellite captured the aerial extent of the flooding in Galena from space. Below is the extent of the Yukon River last year on May 27, and the second picture is the widespread flooding behind the ice Jam on May 28th of this year.

Above is the erupting Pavlof Volcano on May 18, 2013 taken from the ISS. It is located between Sand Point and Cold Bay on the Alaska Peninsula. The Volcano just to the right of Pavlof is Pavlof’s Sister, and is also a volcano.

A summary of the recent Pavlof eruption with a few more ISS photos can be found HERE.

This most recent eruption of Pavlof Volcano was downgraded by the Alaska Volcano Observatory on May 28th as activity subsided.

Wow! Monster Hurricane on Saturn Spied by NASA Spacecraft

/1 Comment/in , /by

Photo Credit: NASASpectacular new images from a NASA spacecraft orbiting Saturn have captured the most detailed views ever of an enormous hurricane churning around the ringed planet’s north pole.

The stunning new images and video of the Saturn hurricane, which were taken by NASA’s Cassini probe, show that the storm’s eye is 1,250 miles (2,000 kilometers) wide — about 20 times bigger than typical hurricane eyes on Earth. And the Saturn maelstrom is more powerful than its Earth counterparts, with winds at its outer edge whipping around at 330 mph (530 km/h).

“We did a double take when we saw this vortex because it looks so much like a hurricane on Earth,” Cassini imaging team member Andrew Ingersoll, of Caltech in Pasadena, said in a statement. “But there it is at Saturn, on a much larger scale, and it is somehow getting by on the small amounts of water vapor in Saturn’s hydrogen atmosphere.”

Saturn’s hurricane swirls inside a mysterious, six-sided vortex. Unlike hurricanes on Earth, which tend to drift northward as our planet rotates, the Saturn storm and its hexagonal vortex have been camped out at the north pole for a while.

“The polar hurricane has nowhere else to go, and that’s likely why it’s stuck at the pole,” Kunio Sayanagi, a Cassini imaging team associate at Hampton University in Hampton, Va., said in a statement.
