Active galaxies called blazars make up the largest class of objects detected by Fermi's Large Area Telescope (LAT). Massive black holes in the hearts of these galaxies fire particle jets in our direction. Fermi team member Elizabeth...

On July 18, 2012, a fairly small explosion of light burst off the lower right limb of the sun. Such flares often come with an associated eruption of solar material, known as a coronal mass ejection or CME -- but this one did not....

Debris is a portrait of Tofino, BC intertidal artist Pete Clarkson as he crafts his most ambitious and personal project to date: a memorial to the 2011 Great East Japan earthquake and tsunami. He, like so many of us around the world, was...

August 1972, as NASA scientist Ian Richardson remembers it, was hot. In Surrey, England, where he grew up, the fields were brown and dry, and people tried to stay out of the Sun, indoors and televisions on. But for several...

This video explains how soldiers made raids on enemy trenches. Part 6 of a 7 part series

An international team of astronomers using data from NASA's Hubble Space Telescope has detected significant changes in the atmosphere of a planet located beyond our solar system. The scientists conclude the atmospheric...

On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions...

In late March 2011, NASA's Swift satellite alerted astronomers to intense and unusual high-energy flares from a new source in the constellation Draco. They soon realized that the source, which is now known as Swift J1644+57,...

In February 2020, NASA’s Solar Dynamics Observatory — SDO — is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the Sun, studying how the Sun creates solar activity and...

Gout | Causes, Pathophysiology, Risk Factors, Symptoms, Diagnosis, Treatment



Gout is a crystal inflammatory monoarthropathy caused by deposition of monosodium urate crystals into joints and other areas of the body. In this...

NASA scientists answer some common questions about the sun, space weather, and how they affect the Earth. This is a two-part series.



Part Two

addresses:

1. Do all flares and CM

Es affect the...

Capturing an image in 10 different wavelengths of light every 12 seconds, NASA’s Solar Dynamics Observatory — SDO — has provided an unprecedentedly clear picture of how massive explosions on the Sun grow and erupt ever since...

In this video, the teacher discusses the palmaris longus muscle, a variable muscle in the human body that some people are born without. The teacher explains the function of the muscle, its evolution, and provides a test for viewers to...

NASA Scientist Holly Gilbert discusses recent sunspot activity during Live Shot. This is a Canned Interview.<b<b<br/>r/>r/>

The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the...

If any of these energy bombs hit Earth, humanity’s satellites, internet and electrical systems will fry and burn out.
