Often, comets are portrayed as harbingers of gloom and doom in movies and on television, but most pose no threat to Earth. Comet Elenin, the latest comet to visit our inner solar system, is no exception. Elenin will pass about 22 million miles (35 million kilometers) from Earth during its closest approach on Oct. 16, 2011.


Trajectory of comet Elenin. …

In early June the Mars500 crew celebrated their one full year inside the modules simulating an interplanetary spaceship. They are now flying virtually back to Earth and due to a delay in communications, introduced to make the simulation more real, some material reaches the outside world slowly. As they get nearer to Earth the
communications delay is reduced.

By September …

Imagine forecasting a hurricane in Miami weeks before the storm was even a swirl of clouds off the coast of Africa or predicting a tornado in Kansas from the flutter of a butterfly’s wing in Texas. These are the kind of forecasts meteorologists can only dream about.

Could the dream come true? A new study by Stanford researchers suggests that …

Two studies appearing in the Aug. 25 issue of the journal Nature provide new insights into a cosmic accident that has been streaming X-rays toward Earth since late March. NASA’s Swift satellite first alerted astronomers to intense and unusual high-energy flares from the new source in the constellation Draco.


On March 28, 2011, NASA’s Swift detected intense X-ray flares thought …

Scientists using data from NASA’s Wide-field Infrared Survey Explorer (WISE) have discovered six “Y dwarfs”– star-like bodies with temperatures as cool as the human body.


This artist’s conception illustrates what a “Y dwarf” might look like. Y dwarfs are the coldest star-like bodies known, with temperatures that can be even cooler than the human body. NASA’s Wide-field Infrared Survey Explorer …

For the first time, a spacecraft far from Earth has turned and watched a solar storm engulf our planet. The movie, released today during a NASA press conference, has galvanized solar physicists, who say it could lead to important advances in space weather forecasting.

“The movie sent chills down my spine,” says Craig DeForest of the Southwest Research Institute in …
