On Feb. 26, 2017, an annular eclipse of the sun was visible along a narrow path that stretched from the southern tip of South America, across the Atlantic Ocean and into southern Africa. Those lucky enough to find themselves in the eclipse’s path saw a fiery ring in the sky. Meanwhile, NASA’s Terra satellite saw the eclipse from space. [ Go.nasa.gov Link ]
On Feb. 26, a “ring of fire” will be visible in the sky above parts of the Southern Hemisphere, including Chile, Argentina and Angola. This is called an annular eclipse.

If you live within the viewing area, even though most of the sun will be obscured by the moon, it’s essential to observe eye safety. This includes using a proper solar filter or an indirect viewing method during ALL phases...

A solar prominence performed a delicate dance over the sun’s edge in this footage captured by NASA’s Solar Dynamics Observatory on Feb. 20, 2017. Prominences are unstable clouds of solar material suspended above the sun’s surface by magnetic forces. The bright area near the bottom of the frame is an active region. This footage was observed in extreme ultraviolet light, a type of light that is...

One down, three to go!

The first of four sounding rockets scheduled for launch from the Poker Flat Research Range in Alaska to examine the structure of auroras was launched at 5:14 a.m. EST, Feb. 22, 2017. [ Go.nasa.gov Link ]
On Feb. 17, 2017, NASA's Time History of Events and Macroscale Interactions during Substorms, or THEMIS, mission marked its 10th anniversary in space. The spacecraft have now spent a decade discovering how mass and energy move through the near-Earth environment in order to determine the physical processes initiating auroras – and they’re still making new discoveries.

The five THEMIS spacecraft were launched 10 years ago today to study near-Earth space. Learn more about this mission:
Twice a year, NASA’s Solar Dynamics Observatory, or SDO, has an eclipse season — a weeks-long period in which Earth blocks SDO’s view of the sun for part of each day. This footage captured by SDO on Feb. 15, 2017, shows one such eclipse. Earth’s edge appears fuzzy, rather than crisp, because the sun’s light is able to shine through Earth’s atmosphere in some places. These images were captured...

About 21 years ago, team members started building and testing the Sounding of the Atmosphere using Broadband Emission Radiometry, or SABER instrument. Back then, they dreamed of how great two years of data from an unexplored region of the upper atmosphere would be.

Now, 15 years later, SABER aboard the Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics, or TIMED, spacecraft has...

The Ionospheric Connection Explorer (ICON) launches this summer to study Earth's interface to space. This video has more info on what ICON will measure!
Meet Marilia. She studies the space environment between Earth and the sun -- in part by launching sounding rockets into auroras.
A NASA sounding rocket to be launched from the Poker Flat Research Range, Alaska, between February 15 and March 3, 2017, will form white artificial clouds during its brief, 10-minute flight to allow scientists on the ground to visually track the winds within the aurora. [ Go.nasa.gov Link ]

The Solar Dynamics Observatory (SDO) was launched seven years ago today, and it has kept a near-constant eye on the sun ever since. Check out how our star has changed since 2010 with seven years of solar views from this sun-watching satellite, all in just over a minute.

On Feb. 9, 2017, NASA’s Magnetospheric Multiscale mission, known as MMS, began a three-month long journey into a new orbit. MMS flies in a highly elliptical orbit around Earth and the new orbit will take MMS twice as far out as it has previously flown. In the new orbit, which begins the second phase of its mission, MMS will continue to map out the fundamental characteristics of space around...

The first total solar eclipse in the continental United States in nearly 40 years takes place on Aug. 21, 2017. Beyond providing a brilliant sight in the daytime sky, total solar eclipses provide a rare chance for scientists to collect data only available during eclipses. NASA is funding 11 scientific studies that will take advantage of this opportunity.

“When the moon blocks out the sun...

The search for life beyond Earth starts in habitable zones, the regions around stars where conditions could potentially allow liquid water – which is essential for life as we know it – to pool on a planet’s surface. New NASA research suggests some of these zones might not actually be able to support life due to frequent stellar eruptions – which spew huge amounts of stellar material and...

The drawing on the left is believed to be the first direct observation of a coronal mass ejection, a giant eruption on the sun that can send billions of tons of matter out into space. Today, we watch for coronal mass ejections with satellites, as seen on the right.
