The image, taken by Expedition 41 aboard the International Space Station, looks like the fine artwork of some extra-terrestrial, but it’s actually decades old scarred earth and entrenchments of warfare along the Iraq/Iran border.
On February 6, 2015, Jupiter comes closest to Earth on its opposition date, coming to within 404 million miles (650 million kilometers) of Earth. Earth passes more or less between the sun and Jupiter, placing Jupiter opposite the sun in our sky. Astronomers call this event an opposition of Jupiter.
Minutes before the sun dawned on the coast of central California on Saturday 31 Jan, NASA looked to the skies, and launched a critical part of its Earth Sciences mission into Low-Earth Orbit. As floods make their way through parts of the country, and as a historic drought continues to punish the farmlands, scientists will now be able to more accurately observe and monitor moisture levels within the land itself, through an orbiting observatory named SMAP.
A new space telescope concept, named the Aragoscope after French scientist Francois Arago who first detected diffracted light waves around a disk, could allow scientists to image space objects like black hole “event horizons” and plasma swaps between stars, said Cash of CU-Boulder’s Center for Astrophysics and Space Astronomy.
We Earthlings love to dream, conjure and extrapolate. If you pose a question such as, “What if Earth had Saturn’s rings?” with all the resources available these days someone will not only answer the question but create some beautiful graphics to depict it!
Supernovae are powerful explosions in space which are triggered when massive stars die. These stellar events forge many different elements — including potassium, iodine, and iron—which are essential for life. But a recent report explains that these events also release heavier elements too — like gold and lead — and radioactive elements — like plutonium and uranium — which counters some of the current ideology.
Most people are well aware by now that the human impact on Earth’s ecosystems is rarely positive. But what about the oceans, those vast, unyielding expanses of biodiversity? A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them.
The Mayan civilization is known to be one of the most sophisticated civilizations in America prior to the Spanish colonization of the region. Its sudden collapse sometime between the 8th and 9th century is also one of the mysteries that baffled experts and which has given rise to a number of theories including overhunting, deforestation and even alien invasion.
An asteroid, called 2004 BL86, will sweep safely past Earth on January 26, 2015. The flyby is notable because 2004 BL86 will be the closest of any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027. This asteroid is estimated from its reflected brightness to be about 500 meters in diameter (about a third of a mile, or 0.5 km).
What would happen if the moon were replaced by various planets in the sky? One YouTube user has taken a look at this hypothetical scenario – and the results are rather impressive.
In a recent development that Hollywood could only hope for, a former NASA employee is claiming that there was a secret manned mission in the 1970s, and that the space agency covered it up. The woman, identified only as “Jackie,” said she was part of the team monitoring the Viking Lander expedition in 1979, and that she saw human figures on Mars.
During his six-month “Blue Dot” mission on the International Space Station, German astronaut Alexander Gerst would often leave his camera running while he worked and did experiments.
