Confirmed by Nasa. Mars Rover Records UFO Streaking Across The Martian Sky, May 2013.

marsstreak

Date of discovery: May 2013 Location of discovery: Mars Eyewitness states: Observing the sky with the green filter of it panoramic camera, the Mars Exploration Rover Spirit came across a surprise: a streak across the sky. The streak, seen in the middle of this mosaic of images taken by the navigation and panoramic cameras, was [...]

NASA pinpoints causes of 2011 Arctic ozone hole

Maps of ozone concentrations over the Arctic come from the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite. The left image shows March 19, 2010, and the right shows the same date in 2011. March 2010 had relatively high ozone, while March 2011 has low levels - Credit: NASA/Goddard

A combination of extreme cold temperatures, human-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds. Even when both poles of the planet undergo ozone losses during the winter, the Arctic’s ozone depletion tends to be milder and shorter-lived than the Antarctic’s. [...]

Pan-Starrs: astonomers warned to avoid danger to their eyes from bright comet

Comet C/2011 L4 (PANSTARRS) is a non-periodic comet discovered in June 2011 that is expected to be visible to the naked eye when it is near perihelion in March 2013.[3][4] The comet was discovered using the Pan-STARRS telescope located near the summit of Haleakala, on the island of Maui in Hawaii.

Astronomers should beware of the danger to their eyes if they try to catch a glimpse of a comet which won’t be seen on earth again until the year 112,000. The C/2011 L4, also known as Comet Pan-Starrs, is making a rare visit to the inner solar system in the middle of this week, and [...]

Astronomers find ‘lost’ supernova

PS1-12sk PS1-12sk, the yellow dot at image center (circled), is classified as a very rare Type Ibn supernova - only the sixth such example found out of thousands of supernovae. It was discovered on the outskirts of a bright elliptical galaxy (the yellow blob to the upper left of the supernova) located about 780 million light-years from Earth. A Type Ibn supernova is thought to come from the explosion of a young, massive star. However, the site of the explosion shows no signs of recent star formation, and a supernova from a massive star has never before been seen in a galaxy of this type - Credit: CfA / PS1 Science Consortium

The star Eta Carinae is ready to blow. 170 years ago, this 100-solar-mass object belched out several suns’ worth of gas in an eruption that made it the second-brightest star after Sirius. That was just a precursor to the main event, since it will eventually go supernova. Supernova explosions of massive stars are common in [...]

NASA: We’ve discovered a previously unknown surprise circling Earth

3rings

NASA’s recently deployed Van Allen probes — a pair of robotic spacecraft launched just last August to investigate Earth’s eponymous pair of radiation belts — are already turning out some very unexpected findings. Chief among them: an ephemeral third ring of radiation, previously unknown to science, surrounding our planet. NASA says the discovery was a [...]

Journey to the limits of spacetime

3-D snapshot for an evolved Black Hole (BH) model. The disk and jet near the BH are aligned with the BH spin axis and point mostly in and out of the figure plane, whereas at larger distances the jet points roughly halfway between the BH spin axis and the disk's rotational axis (pointing along the orange cylinder) - Credit: University of Texas at Austin, Texas Advanced Computing Center

Voracious absences at the center of galaxies, black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy. “Over its lifetime, a black hole can release more energy than all the stars in a galaxy combined,” said Roger Blandford, director of the Kavli Institute [...]

A simple view of gravity does not fully explain distribution of stars in crowded clusters

Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity. After analyzing Hubble Space Telescope images of star cluster NGC 1818 in the Large Magellanic Cloud, a satellite galaxy of the [...]

The time has come for humanity to journey to the planet Mars

marssocity

We’re ready. Though Mars is distant, we are far better prepared today to send humans to the Red Planet than we were to travel to the Moon at the commencement of the space age. Given the will, we could have our first crews on Mars within a decade. The reasons for going to Mars are [...]

Documentary: The Mars Underground

marss

A very well-crafted documentary with excellent special effects and awesome musical score that outline a basic, affordable and realistically plausible plan for the human exploration of the red planet in the very near future — as few as just 10 years away (if it can be funded). It shows Dr. Robert Zubrin, aerospace engineer and [...]

New Asteroid-Mining Space Fleet Venture to Be Unveiled Today (watch live)

dsi_logo

The world’s first fleet of commercial asteroid-prospecting spacecraft will be announced at 10 a.m. Tuesday, Jan. 22, at the Santa Monica Museum of Flying by a new company, Deep Space Industries Inc. Host Geoff Notkin of the Science Channel’s Meteorite Men series will introduce the Deep Space founders – who include leaders in the space [...]
