The full image of Mars shown in the latest of a series of photos from India’s Mars Orbiter Mission (MOM) has generated much interest within the country and in planetary circles.

While those at home chose to see an image of India on the Martian surface, at the Planetary Society the image has been welcomed for its superior detail, coming years after Hubble clicked one 11 years ago.

“A data set unlike any generated before by any other mission, the MOM’s picture Continue reading

French meteorologists have issued a red alert – the maximum warning – to residents in southern France due to heavy storms and the threat of flash flooding. Four people were killed in raging flood waters in the same area two weeks ago.

Residents in the Hérault department on the Mediterranean coast were under a red alert on Monday because of storms heavy rain just two weeks after four people were killed by raging flood waters in the area.

Downpours since midday on Monday left local authorities concerned enough about th Continue reading

Simulations Reveal An Unusual Death For Ancient Stars

http://earthchangesmedia.com/simulations-reveal-an-unusual-death-for-ancient-stars
Certain primordial stars—those 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind….

Certain primordial stars—those 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind.

Astrophysicists at the University of California, Santa Cruz (UCSC) and the University of Minnesota came to this conclusion after running a number of supercomputer simulations at the Department of Energy’s (DOE’s) Na Continue reading

Rachel has weakened into a tropical storm over the Pacific off Mexico’s coast and poses no threat to land.

The storm’s maximum sustained winds Monday morning are about 60 mph (95 kph).

The storm is centered about 485 miles (780 kilometers) west of the southern tip of Mexico’s Baja California peninsula and is moving north at 2 mph (4 kph).

The U.S. National Hurricane Center says the storm is likely to weaken steadily over the next two days. It is expected to become nearly stationary later Monday, then drift to Continue reading

Tropical Storm Phanfone, formed this past weekend in the western Pacific Ocean, and is slowly gathering strength north-northeast of Guam. Phanfone could eventually pose a threat as a strong typhoon next week. Let’s break down what we know now.

First up for Phanfone are the Mariana Islands.

While the center of Phanfone will track well north of Guam, a tropical storm warning and a typhoon watch are posted for the northern Mariana Islands including Saipan, Tinian, Pagan, Alamagan and the surrounding waters.

Phanfo Continue reading

Set to launch in 2017, NASA’s Transiting Exoplanet Survey Satellite (TESS) will monitor more than half a million stars over its two-year mission, with a focus on the smallest, brightest stellar objects.

During its observations, TESS is expected to find more than 3,000 new planets outside of our solar system, most of which will be possible for ground-based telescopes to observe.

“Bright host stars are the best ones for follow-up studies of their exoplanets to pin down planet masses, and to Continue reading

One of the big questions in cosmology regards the shape of the universe. “Shape” in this case is not the distribution of galaxies, but rather the shape of space and time itself. In general relativity, space and time can be warped by masses (producing the effect of gravity), and it can be warped by dark energy (producing cosmic expansion). Knowing the shape of the cosmos lets us determine if it is finite in size or infinite, and whether it will expand forever or collapse back upon itself.

It’s generally thought that the u Continue reading
