MAVEN results find Mars behaving like a rock star

If planets had personalities, Mars would be a rock star according to recent preliminary results from NASA's MAVEN spacecraft. Mars sports a "Mohawk" of escaping atmospheric particles at its poles, "wears" a layer of metal ...

NASA's SDO sees giant January sunspots

An enormous sunspot, labeled AR1944, slipped into view over the sun's left horizon late on Jan. 1, 2014. The sunspot steadily moved toward the right, along with the rotation of the sun, and now sits almost dead center, as ...

SDO reveals how magnetic cage on the Sun stopped solar eruption

A dramatic magnetic power struggle at the Sun's surface lies at the heart of solar eruptions, new research using NASA data shows. The work highlights the role of the Sun's magnetic landscape, or topology, in the development ...

Using maths to unravel the Sun's magnetic fields

Complex magnetic fields in the Sun's atmosphere help heat it to multi-million degree temperatures and create explosive events such as solar flares that affect us here on Earth.

Image: Majestic solar eruption larger than Earth

A gigantic ribbon of hot gas bursts upwards from the Sun, guided by a giant loop of invisible magnetism. This remarkable image was captured on 27 July 1999 by SOHO, the Solar and Heliospheric Observatory. Earth is superimposed ...

Discovering trailing components of a coronal mass ejection

Using Green Bank Observatory in West Virginia, PSI Associate Research Scientist Elizabeth A. Jensen's team observed radio signals from the MESSENGER spacecraft and discovered that solar eruptions known to cause communication ...

To uncover the secrets of exoplanets, try listening to them

From rainfall patterns to share price performance, the usual way to analyse any data that shows something changing over a period of time is to put it into a graphic. Making data visual usually makes it much easier to understand ...

First X-class solar flare of 2013

(Phys.org) —On May 12, 2013, the sun emitted a significant solar flare, peaking at 10 p.m. EDT. This flare is classified as an X1.7, making it the first X-class flare of 2013. The flare was also associated with another ...
