IBEX Reveals a Missing Boundary At the Edge Of the Solar System

05.10.2012
Scientists compile data from IBEX, NASA's twin Voyager spacecraft, and computer models to show that the heliosphere just isn't moving fast enough to create a bow shock in the tenuous and highly magnetized region in our local part of the galaxy.

Getting Ready for the Next Big Solar Storm

06.22.2011
This week, officials have gathered in Washington DC to ask themselves a simple question: What if it happens again? The purpose of Space Weather Enterprise Forum (SWEF) is to raise awareness of space weather and its effects on society especially among policy makers and emergency responders.

Solstice Flare and CME - UPDATE

06.22.2011
A CME propelled toward Earth on June 21 may be moving slower than originally thought. Our Space Weather Lab analysts have downgraded the probable speed to 400 mph (650 km/s). Impact is now expected June 24 at 3am EDT (0700 UT). Forecasters now predict a relatively mild G1-class geomagnetic storm when the cloud arrives.

FASTSAT Mission Update

06.20.2011
The Plasma Impedance Spectrum Analyzer (PISA) has now completed more than 120 days over the course of six months since it was first turned on. The Miniature Imager for Neutral Ionospheric Atoms and Magnetospheric Electrons (MINI-ME) is functioning well after six months in space. The Thermospheric Temperature Imager (TTI) has collected more than 50 days of data.

New Insights On How Solar Minimums Affect Earth

06.15.2011
The number of sunspots can change from cycle to cycle and 2008 saw the longest and weakest solar minimum since scientists have been monitoring the sun with space-based instruments.

Recalculating the Distance to Interstellar Space

06.15.2011
Scientists analyzing recent data from NASA's Voyager and Cassini spacecraft have calculated that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought.

A Big Surprise from the Edge of the Solar System

06.14.2011
Voyager data beamed back from their current location has lead to new computer models that show the edge of our solar system is not smooth, but filled with a turbulent sea of magnetic bubbles.

Researchers Crack the Mystery of the Missing Sunspots

03.02.2011
In 2008-2009, sunspots almost completely disappeared for two years. It was a big event, and solar physicists openly wondered, 'Where have all the sunspots gone?'

FASTSAT Mission Update.

01.27.2011
Over December 2010 and January 2011, testing continued on two of FASTSAT's three onboard science instruments. The Plasma Impedance Spectrum Analyzer (PISA) and the Miniature Imager for Neutral Ionospheric Atoms and Magnetospheric Electrons (MINI-ME). The third science instrument, the Thermosphere Temperature Imager (TTI), is scheduled for activation on February 1st.

Kuiper Belt of Many Colors

11.01.2010
A new computer model maps out the right combination of materials and space environment that could produce some of those lovely hues. The model suggests that these objects have many layers, and that the red colors of one particularly interesting group of these objects -- the so-called Cold Classical Kuiper Belt -- could come from organic materials in the layer just under the crust.
