IBEX and TWINS Observe a Solar Storm

Sun spewed a two million mile per hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere on April 5, 2010. As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm that interfered with commands to a communications satellite, Galaxy-15, which subsequently foundered and drifted, taking almost a year to return to its station.

The Giant Ridge Around Middle of Iapetus

As said researchers the giant ridge around the middle of Saturn moon’s Iapetus that makes it resemble an oversize walnut may have essentially formed as a “hug” from a dead moon. Iapetus, the third-largest of Saturn’s moons. This enormous ridge wraps along its equator, reaching up to 12.4 miles (20 kilometers) high and 124 miles (200 km) wide, and encircles more than 75 percent of the moon. Altogether, the ridge may constitute about one-thousandth the mass of Iapetus.

Study of Weather Based on the Climate of Alien Planets

The U.K. agency tasked with monitoring the country’s weather forecasts is expanding its research on how space weather affects Earth and the atmospheres of alien planets around other stars. The U.K. Met Office, which is funded by the government to provide national weather services, is now also planning to supply space weather forecasts for the region. Two teams of scientists presented their research at the U.K.-Germany National Astronomy Meeting held in March in Manchester, England.

New Observations of Giant Elliptical Galaxy Centaurus A

New Infrared and X-ray observations from two space telescopes strengthen the view that the galaxy may have been created by the cataclysmic collision of two older galaxies. The infrared light was captured by the European Space Agency’s Herschel Space Observatory. The X-ray observations were made by the European Space Agency’s XMM-Newton space telescope. Centaurus A is the closest giant elliptical galaxy to Earth, at a distance of around 12 million light-years.

Texas Tornadoes Seen by GOES Satellite

Tornadoes tore through northeast Texas on April 3, in an outbreak of severe weather that was captured by a fleet of satellites designed to monitor the situation from space. At least six tornadoes were reported in the Dallas-Fort Worth area from mid-afternoon to early evening on April 3, according to officials at the National Weather Service. NOAA’s Geostationary Operational Environmental Satellite, GOES-13, captures visible and infrared images of weather over the eastern U.S. every 15 minutes, and captured the movement of the weather system that generated the Texas twisters.

Ultraviolet Image of Cygnus Loop Nebula

NASA’s Galaxy Evolution Explorer satellite (GALEX) snapped a spectacular photo of a wispy blue nebula with an odd twist. It looks like a giant human head in deep space. NASA’s Galaxy Evolution Explorer (GALEX), which took the Cygnus Loop nebula photo, was launched in April 2003 on a mission to map vast areas of the sky in the ultraviolet range of the light spectrum. The spacecraft completed its primary mission in 2007 and was placed in standby mode as engineers prepare to shut it down for good later this year.

Solar Storm Blasted Earth With Powerful Dose of Energy

According to Nasa scientists a recent spate of furious eruptions on the surface of the sun hurled a huge amount of heat toward Earth. This is the biggest dose our planet has received from our closest star in seven years. Although the influx of solar energy puffed up the atmosphere, increasing drag on low-orbiting satellites, it caused fewer disruptions to electronic infrastructure such as electronic grids than some expected.

Global Geologic Map of Jupiter Moon Io

Scientists have created a global geologic map of Jupiter’s moon Io, the most volcanically active object in the solar system.The map, which was published this week by the U.S. Geological Survey (USGS), shines a light on Io, the fourth-largest satellite in the solar system. Scientists hope the new tool will help them better understand the exotic moon. According to David Crown, of the Planetary Science Institute in Tucson, Ariz.

Origin of Important Supernova Class

Studies using X-ray and ultraviolet observations from NASA’s Swift satellite provide new insights into the elusive origins of an important class of exploding star called Type Ia supernovae. These explosions, which can outshine their galaxy for weeks, release large and consistent amounts of energy at visible wavelengths. These qualities make them among the most valuable tools for measuring distance in the universe.
