A team of NASA scientists and engineers now believes it can leverage recent advances in a greenhouse-detecting instrument to build the world’s first space-based sodium lidar to study Earth’s poorly understood mesosphere.

Scientist Diego Janches and laser experts Mike Krainak and Tony Yu, all of whom work at NASA Goddard in Greenbelt, Maryland, are leading a research-and-development effort to...

You can’t see them, but swarms of electrons are buzzing through the magnetic environment — the magnetosphere — around Earth. The electrons spiral and dive around the planet in a complex dance dictated by the magnetic and electric fields. When they penetrate into the magnetosphere close enough to Earth, the high-energy electrons can damage satellites in orbit and trigger auroras. Scientists...

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather — which can include changes in Earth's magnetic environment — are usually triggered by the sun’s activity, but recently declassified data on high-altitude nuclear explosion tests have provided a new look at the mechanisms that set off perturbations in that...

Humans have long been shaping Earth’s landscape, but now scientists know we can shape our near-space environment as well. A certain type of communications — very low frequency, or VLF, radio communications — have been found to interact with particles in space, affecting how and where they move. At times, these interactions can create a barrier around Earth against natural high energy particle...

At the edge of the sun, a large prominence and a small prominence began to shift, turn and fall apart in this footage captured May 8-9, 2017. Prominences are notoriously unstable, and here, competing magnetic forces pulled the solar material back and forth until the prominences dissipated. These images were taken in a wavelength of extreme ultraviolet light, which is typically invisible to our...

Good things come in petit packages!

A cereal box-sized spacecraft, petitSat (short for Plasma Enhancements in The Ionosphere-Thermosphere Satellite), will help us understand how bubbles and blobs of plasma in our atmosphere can affect communications, GPS, and radar signals. [ Go.nasa.gov Link ]

Our ever-changing sun continuously shoots solar material into space. The grandest such events are massive clouds that erupt from the sun, called coronal mass ejections, or CMEs. These solar storms often come first with some kind of warning — the bright flash of a flare, a burst of heat or a flurry of solar energetic particles. But another kind of storm has puzzled scientists for its lack of...

Strands of solar material at the sun's edge shifted and twisted back and forth over a 22-hour period in this footage captured May 2-3, 2017, by NASA’s Solar Dynamics Observatory. In this close-up, the strands are being manipulated by strong magnetic forces associated with active regions. To give a sense of scale, the strands that hover above the sun are more than several times the size of...

Our Magnetospheric Multiscale Mission, or MMS, is on a journey to study a new region of space.

On May 4, 2017, after three months of precisely coordinated maneuvers, MMS reached its new orbit to begin studying the magnetic environment on the ever-rotating nighttime side of Earth. The new orbit will allow the spacecraft to study magnetic reconnection on the night side of Earth, where the...

On May 5, 2017, scientists will launch a sounding rocket 200 miles up into the atmosphere, where in just five minutes, it will take 1,500 images of the sun. The NASA-funded RAISE mission is designed to scrutinize split-second changes occurring near the sun’s active regions — areas of intense, complex magnetic activity that can give rise to solar flares, which eject energy and solar material...

This full-size mock-up of the Ionospheric Connection Explorer, or ICON, was used by engineers to help evaluate the placement of ICON’s instruments on the spacecraft. The mock-up was made by the Space Dynamics Laboratory at Utah State University in Logan, which is responsible for integrating and testing ICON. These photos show the ICON mock-up at Cal Day, an annual open house at UC Berkeley,...

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by NASA’s Solar Dynamics Observatory on April 24-26, 2017. The arches are traced out by charged particles spinning along the magnetic field lines. These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in...

From long, tapered jets to massive explosions of solar material and energy, eruptions on the sun come in many shapes and sizes. Scientists from Durham University and NASA now propose that a universal mechanism can explain the whole spectrum of solar eruptions. They used 3-D computer simulations to demonstrate that a variety of eruptions can be thought of as the same kind of event, only in...

Launched on April 25, 2007, NASA’s Aeronomy of Ice in the Mesosphere, or AIM, mission, has provided a wealth of new science on the dynamics and composition of Earth’s upper atmosphere. Designed to study noctilucent, or night-shining, clouds, AIM’s data have helped scientists understand a host of upper-atmosphere phenomena, from radio echoes to giant, planet-scale atmospheric waves.

New data from NASA’s Cassini mission, combined with measurements from the two Voyager spacecraft and NASA’s Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system of magnetic field from the sun — calling into question the alternate view of the solar magnetic fields trailing behind the sun in the shape of a long comet tail.
