UFO found on the Baltic sea floor?

On June 19th the Swedish-based diving company Ocean Explorer discovered something they’ve never quite seen before. They were exploring in the Baltic Sea between Sweden and Finland looking for sunken treasures when a very unusual image suddenly appeared on the sonar.  A 197 feet diameter cylinder shaped object was discovered at the depth of approximately 275 feet.  Treasure hunters, Peter Lindberg, Dennis Aasberg are in the midst of planning for their next excursion; to find out what’s there, and how it ended up in the Baltic Sea. Ocean Explorer’s Operation Baltic Discovery will unveil what people around the world are waiting to find out- What’s really there?

NASA Announces 11 New Planetary Systems

NASA's Kepler mission has discovered 11 new planetary systems hosting 26 confirmed planets. These discoveries nearly double the number of verified Kepler planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star. Such systems will help astronomers better understand how planets form.

This artist's concept shows an overhead view of the orbital position of the planets in systems with multiple transiting planets discovered by NASA's Kepler mission. All the colored planets have been verified. More vivid colors indicate planets that have been confirmed by their gravitational interactions with each other or the star. Several of these systems contain additional planet candidates (shown in grey) that have not yet been verified. Image credit: NASA Ames/UC Santa Cruz

 

The planets orbit close to their host stars and range in size from 1.5 times the radius of Earth to larger than Jupiter. Fifteen are between Earth and Neptune in size. Further observations will be required to determine which are rocky like Earth and which have thick gaseous atmospheres like Neptune. The planets orbit their host star once every six to 143 days. All are closer to their host star than Venus is to our sun.

Asteroid 2012 BX34

Newly-discovered asteroid 2012 BX34 will fly past Earth on Jan. 27th only 77,000 km (0.2 lunar distances) away. There is no danger of a collision with the 14-meter wide space rock. Advanced amateur astronomers might be able to observe the flyby as the asteroid brightens to 14th magnitude just before closest approach on Friday at 1530 UTC.

The Rings of Pluto?

Like other bodies in the outer Solar System, Pluto may have have rings orbiting it. Finding these rings could be important for the safety of NASA's New Horizons mission - currently en route to the tiny world.

Instruments will map Pluto and its moon, Charon, providing detail not only on the surface of the dwarf planet, but also about its shape, which could reveal whether or not an ocean lies beneath the ice.

In the distant outer Solar System, rings are nearly ubiquitous. Jupiter, Saturn, Uranus, and Neptune all have rings, leaving Pluto as the only outer planet without rings.

Study Shows Our Galaxy Has at Least 100 Billion Planets

This artist's illustration gives an impression of how common planets are around the stars in the Milky Way galaxy. The planets, their orbits, and their host stars are all vastly magnified compared to their real separations. A six- year search that surveyed millions of stars using the microlensing technique concluded that planets around stars are the rule rather than the exception. The average number of planets per star is greater than one. Image credit: NASA/ESA/ESO. Click to enlarge.

Our Milky Way galaxy contains a minimum of 100 billion planets, according to a detailed statistical study based on the detection of three planets located outside our solar system, called exoplanets.

The Dunes Of Titan

A new analysis of radar data from NASA's Cassini mission, in partnership with the European Space Agency and the Italian Space Agency, has revealed regional variations among sand dunes on Saturn's moon Titan. The result gives new clues about the moon's climatic and geological history.

Data from NASA's Cassini spacecraft show that the sizes and patterns of dunes on Saturn's moon Titan vary as a function of altitude and latitude.

Dune fields are the second most dominant landform on Titan, after the seemingly uniform plains, so they offer a large-scale insight into the moon's peculiar environment. The dunes cover about 13 percent of the surface, stretching over an area of 4 million square miles (10 million square kilometers). For Earthly comparison, that's about the surface area of the United States.

Big Solar Flare Today

This morning, Jan. 23rd around 0359 UT, big sunspot 1402 erupted, producing a long-duration M9-class solar flare. The explosion's M9-ranking puts it on the threshold of being an X-flare, the most powerful kind.

NASA's Solar Dynamics Observatory captured the flare's extreme ultraviolet flash:

The Solar and Heliosphere Observatory (SOHO) and the STEREO-Behind spacecraft have both detected a CME rapidly emerging from the blast site. Analysts at the Goddard Space Weather Lab estimate a velocity of 2200 km. There is little doubt that the cloud is heading in the general direction of Earth. A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth's magnetic field on Jan. 24-25 as it sails mostly north of our planet.

Mars Meteorites Fall in Morocco

In July 2011, a rare martian meteorite fell to Earth - the first in about 50 years. The meteorite could hold clues to the history of the martian environment and the potential for life on the red planet.

Arizona State University’s (ASU) Center for Meteorite Studies has acquired a significant new sample for its collection: a rare martian meteorite that fell in southern Morocco in July 2011. It is the first martian fall in about 50 years.
