On Aug. 21, 2017, scientists are looking to this year’s total solar eclipse passing across America to improve our modeling capabilities of Earth’s energy. [ Go.nasa.gov Link ]

Guoyong Wen, a NASA scientist working for Morgan State University in Baltimore, is leading a team to gather data from the ground and satellites before, during and after the eclipse so they can simulate this year’s... View more »

A medium-sized flare and a coronal mass ejection erupted from the same large active region in this footage captured on July 14, 2017, by NASA’s Solar Dynamics Observatory satellite. The flare lasted almost two hours. When viewing in this wavelength of extreme ultraviolet light — typically invisible to our eyes, but colorized here in gold — we can trace the movement of the sun’s electrically... View more »

Space is not empty, nor is it silent. While technically a vacuum, space nonetheless contains energetic charged particles, governed by magnetic and electric fields, and it behaves unlike anything we experience on Earth. In regions laced with magnetic fields, such as the space environment surrounding our planet, particles are continually tossed to and fro by the motion of various electromagnetic... View more »

Space may seem empty, but it’s actually a dynamic place, dominated by invisible forces, including those created by magnetic fields. Magnetospheres — the areas around planets and stars dominated by their magnetic fields — are found throughout our solar system. They deflect high-energy, charged particles called cosmic rays that are mostly spewed out by the sun, but can also come from... View more »

An active region on the sun — an area of intense and complex magnetic fields — has rotated into view on the sun and seems to be growing rather quickly in this video captured by NASA’s Solar Dynamics Observatory between July 5-11, 2017. Such sunspots are a common occurrence on the sun, but are less frequent as we head toward solar minimum, which is the period of low solar activity during its... View more »

Next month, on Aug. 21, a solar eclipse will be visible--weather permitting--across North America. You can never look directly at the sun, and an eclipse is no exception. Watch this video to learn how to safely watch the Aug. 21 solar eclipse! More at eclipse2017.nasa.gov/safety

A prominence at the edge of the sun provided us with a splendid view of solar material as it churned and streamed in this footage captured June 25-26, 2017, by NASA’s Solar Dynamics Observatory satellite. The charged particles of the solar material, called plasma, are manipulated by strong magnetic forces. When viewed in this wavelength of extreme ultraviolet light—typically invisible to our...

July 4 fireworks came early when a NASA Terrier-Improved Malemute sounding rocket was successfully launched at 4:25 a.m., Thursday, June 29, from NASA's Wallops Flight Facility in Virginia.

During the 8-minute flight, 10 canisters about the size of a soft drink can were ejected in space, 6 to 12 miles away from the 670-pound main payload. The canisters deployed blue-green and red vapor that... View more »

The sun appears to be much the same day-in, day-out, year after year. But astronomers have long known that this is not true: the sun does change. Properly-filtered telescopes reveal a fiery disk often speckled with dark sunspots, which crackle with solar flares—magnetic explosions that illuminate Earth with flashes of X-rays and extreme ultraviolet radiation. The sun is a seething mass of... View more »

Update: The launch of the Colorado High-resolution Echelle Stellar Spectrograph — or CHESS — on a NASA Black Brant IX suborbital sounding rocket was successfully conducted on June 27, 2017, at 1:10 a.m. EDT (June 26 at 11:10 p.m. MDT) from the White Sands Missile Range in New Mexico. Preliminary indications are that a good flight was conducted and science data was received during the flight.

Life on Earth is made possible by its proximity to the sun. Yet even with the protection of our magnetic field, we face a daily barrage of radiation—the solar wind—which flows outward from the sun.

It is never safe to look directly at the sun's rays – even if the sun is partly obscured. When watching a partial eclipse you must wear eclipse glasses at all times if you want to face the sun, or use an alternate indirect method ([ Go.nasa.gov Link ]. This also applies during a total eclipse up until the time when the sun is completely and totally blocked.

During the short time when the moon... View more »

Deep in space between distant stars, space is not empty. Instead, there drifts vast clouds of neutral atoms and molecules, as well as charged plasma particles called the interstellar medium — that may, over millions of years, evolve into new stars and even planets. These floating interstellar reservoirs are the focus of the NASA-funded CHESS sounding rocket mission, which will check out the... View more »

At any given moment, as many as 10 million wild jets of solar material burst from the sun’s surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn’t understand how they form. Now, for the first time, a computer simulation — so detailed it took a full year to run —...
