Massive Planet Gone Rogue Discovered

A massive rogue planet has been discovered in the Beta Pictoris moving group. The planet, called PSO J318.5338-22.8603 (Sorry, I didn't name it), is over eight times as massive as Jupiter. Because it's one of the few directly-imaged exoplanets we know of, and is accessible for study by spectroscopy, this massive planet will be extremely important when piecing together the details of planetary formation and evolution.Most planets outside our solar system are not directly observable.

Gravitational Waves Discovered: A New Window on the Universe

"Ladies and Gentlemen, we have detected gravitational waves. We did it."With those words, Dave Reitze, executive director of the U.S.-based Laser Interferometry Gravitational-Wave Observatory (LIGO), has opened a new window into the universe, and ushered in a new era in space science.Predicted over 100 years ago by Albert Einstein, gravitational waves are ripples in space-time.

NASA Unveils Orion Pressure Vessel at KSC Launching on EM-1 Moon Mission in 2018

KENNEDY SPACE CENTER - NASA officials proudly unveiled the pressure vessel for the agency’s new Orion capsule destined to launch on the EM-1 mission to the Moon in 2018, after the vehicle arrived at the Kennedy Space Center (KSC) in Florida last week aboard NASA’s unique Super Guppy aircraft.This ‘new and improved’ Orion was unloaded from the Super Guppy and moved to a test stand called the ‘birdcage’ in the high bay inside the Neil Armstrong Operations and Checkout (O&C) Building at KSC where it was showcased to the media including Universe Today.Orion’s arrival at KSC truly signifies a major turning point in achieving NASA’s agency-wide goal of sending humans to the Red Planet in the 2030s to carry out the ‘Journey to Mars’ initiative.The Orion pressure vessel serves as the structural backbone for the spacecraft.But before it can launch engineers and technicians from NASA and prime contractor Lockheed Martin will spend the next two years meticulously installing all the systems amounting to over 100,000 components and gear required for flight.This particular ‘Lunar Orion’ crew module is intended for blastoff to the Moon in 2018 on NASA’s Exploration Mission-1 (EM-1) atop the agency’s mammoth new Space Launch System (SLS) rocket, simultaneously under development.
