FBR Capital Markets attended Oracle Corp.’s financial analyst meeting and its annual user conference OpenWorld this week.

In the coming years, as a result of changes, in solar activity, radiation hazards are likely to increase for both air travelers and astronauts.

At a distance of about 13,000 light-years from Earth, it is the closest yellow hypergiant found to date and new observations show it shines some 500,000 times more brightly than the Sun.

A gigantic solar flare that erupted Saturday just won't quit and is forecasted to continue to dazzle sky watchers in Asia and Europe with aurora light shows Tuesday evening.

Particles that were blasted by the sun during a powerful solar flare on Saturday have reached Earth, which will illuminate the Northern Lights in some regions and may also interrupt radio and GPS signals.

Researchers at Princeton University and New York University have developed a ready-made method for detecting the collision of stars with an elusive type of black hole that is believe to make up dark matter.

In 1977, the blockbuster sci-fi movie Star Wars showed a spectacular scene: the lead character Luke Skywalker walks into a binary sunset in the planet Tatooine. Thirty-four years later, such a scene has become a reality. The only difference is that the planet is not called Tatooine but is officially called Kepler-16b.

Scientists say they have discovered 50 new exoplanets, including 16 super-Earths, orbiting nearby stars, making it the largest number of such planets ever announced at one time.

The sun has unleashed a series of solar flares over the last four days, but the good news is none of them are expected to travel directly toward Earth.

The sun has let off some heat this week in the form of unusually strong class solar flares that have blazed from its surface letting of a giant ball of solar material.

The Solar Dynamics Observatory has revealed information on late-phase solar flares.

Middle-aged women, who indulge in moderate consumption of an alcoholic beverage on a regular basis, stand a better chance of staying healthy as they grow older, research shows.

The sun unleashed an unusually strong X2.1-class solar flare on Tuesday which was four times stronger than the earlier M-class flare that erupted on Sept. 6 at about 0150 GMT.

Like the fictitious time bomb in the Hollywood blockbuster Speed, rigged to blow up the bus in which it was planted it slowed below 50 mph, some white dwarf stars when slowed down from their rapid spins may explode as supernova, astronomers say.

The New Orleans region braced for Tropical Storm Lee on Saturday, with the morning marked by some evacuation orders, flooding and tornado warnings.

A set of new still images collected by NASA's Hubble Space Telescope show in unprecedented detail the jets of glowing gas ejected from young stars, providing a peek at how the sun came into existence.

Global warming and climate change are phenomena that broke the bonds of scientific circles to emerge as a matter of debate between believers and skeptics. Countless studies validating and denying global warming have seen the light of the day, providing fodder for more, often somewhat bitter debates. Within the past month, Nobel Prize winner and leading climate change alarmist Al Gore has called those who deny global warming akin to racists, and pseudo-...

It's cool (literally), and the glaciers won't be here forever!

Astronomers have revealed startling facts about how widely separated solar reactions are linked, with one eruption somehow triggering the other.

Astronomers have discovered the densest extrasolar planet made up of diamonds, lying 4000 light years away from Earth in the constellation of Serpens (the Snake).

Scientists have found a way to spot active regions of the sun, a full day or two before they erupt as sunspots, by listening to sound waves from deep inside the sun. This prediction could possibly lead to better forecasts of dangerous solar storms, a new study said.
