Cylinder UFO

There's space junk, decommissioned satellites, and then this bizarre cylinder-shaped object spotted NASA's live web feed earlier this month, traveling alongside the International Space Station. "As I was watching, I noticed a long cylinder object floating alongside and below the space station. Its speed was matched with the ISS, but the object floating was semi-transparent. Just when you thought it was about to come into focus, the screen went blue. That's what happens when Nasa catches a UFO on cam, they cut the feed for a few minutes," said UFO researcher Scott Waring. Click here for a few more cylinder / cigar-shaped UFO sightings.

Saturn Aurora Sounds

NASA's Cassini spacecraft has been detecting intense radio emissions from Saturn's aurorae, where magnetic field lines thread the polar regions. These signals have been shifted into the range of human hearing and compressed in time. The complex radio spectrum with rising and falling tones, is very similar to Earth's auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region. Time on this recording has been compressed, so that 73 seconds corresponds to 27 minutes. Since the frequencies of these emissions are well above the audio frequency range, we have shifted them downward by a factor of 44.

Philip Lubin, a researcher at the University of California at Santa Barbara's Experimental Cosmology Group, has proposed an innovative propulsion method that could eventually transport humans to Mars in 3-days or less. It involves an unmanned spacecraft with a one-meter DE-STAR laser sail that is propelled by aiming a powerful laser at it while still in Earth orbit, thus accelerating the craft to a significant fraction of the speed of light. "As an example, on the eventual upper end, a full scale DE-STAR 4 (50-70 GW) will propel a wafer scale spacecraft with a one meter laser sail to about 26 percent the speed of light in about 10 minutes, reach Mars (1 AU [astronomical unit, the Earth-Sun distance]) in 30 minutes, pass Voyager 1 in less than 3 days, pass 1,000 AU in 12 days and reach Alpha Centauri in about 15 years," said Lubin.

Apollo 10 Strange Sounds

Two months before the famous Apollo 11 moon landing mission in 1969, Apollo 10 entered lunar orbit, which included traversing the dark side of the moon, a place where all spacecraft are out of radio contact with Earth for about 1-hour. Recently declassified tapes reveals that all was not as it seems, as these recordings contained "strange, otherworldly music coming through the Apollo module's radio."

5D Black Hole

Researchers from the University of Cambridge and Queen Mary University of London have suggested that a fifth-dimensional black hole could exist. If one of these were detected, it would lead to the appearance of a 'naked singularity' - a point where gravity is so intense that space, time, and the laws of physics, break down. From simulations, this black hole would be shaped like a very thin ring that gives rise to a series of 'bulges' connected by strings that become thinner over time. Eventually they become so thin that they pinch off into a series of miniature black holes. Continue reading for a video on the fifth-dimension, and more information.

Black Knight Satellite ISS

The Black Knight satellite is claimed by some to be an object approximately 13,000-years-old of extraterrestrial origin - originating from the Epsilon Bootes Star System - orbiting Earth in near-polar orbit, and just this past week, there was an alleged sighting by Russian cosmonauts aboard the ISS. It's claimed to have been captured by the space station's own cameras while it was waiting for a supplies delivery. Click here for more pictures.

Earth Moon Mars

At the time the HiRISE camera on NASA's Mars Reconnaissance Orbiter captured this stunning image, Earth was 88-million miles from the Red Planet. If you looks closely, the west coast outline of South America is visible at lower right, while the exposure of this image was set for the relatively dark Moon. The HiRISE detector in two of the three color channels was saturated due to Earth being so bright, so this version of the image required significant processing. Continue reading to see what Earth and Jupiter look like from Mars.

Gravitational Waves

Phycists at at LIGO - laser interferometer gravitational-wave observatory - have detected gravitational waves for the first time in known history. Einstein's theory states the fabric of space-time can become curved by any massive event in the universe, such as two black holes merging or stars exploding, and these curves ripple out as gravitational waves, similar to dropping a stone in a pond. When these ripples reach Earth, they're tiny (1 billionth of the diameter of an atom), which explains why it's taken so long to find them. Click here for more pictures of the LIGO laboratory.

Gravitational Lensing

In observational astronomy, an Einstein ring is the deformation of the light from a source, such as a galaxy, into a ring through gravitational lensing of the source's light by an object with an extremely large mass, like a black hole. This occurs when the source, lens, and observer are all aligned. The first complete Einstein ring, designated B1938+666, was discovered by collaboration between astronomers at the University of Manchester and NASA's Hubble Space Telescope in 1998. The simulation above depicts a Schwarzschild black hole in front of the Milky Way. The first Einstein ring corresponds to the most distorted region of the picture and is clearly shown by the galactic disc. Click here for the first image in this week's art of trolling gallery.

China Moon Color

H/T: TechCrunch

Yutu is an unmanned lunar rover that formed part of the Chinese Chang'e 3 mission to the Moon, launched at 17:30 UTC on December 1, 2013, and reaching the lunar surface on December 14, 2013. It's the first soft landing on the Moon since 1976 and the first rover to operate there since the Soviet Lunokhod 2 ceased operations back in 1973. This week, the China National Space Administration, has released true color images of its surface from their recent landing. Continue reading to see more.
