Pasadena, CA – New NASA satellite imagery captured a hot lava flow from fissure 8 of Hawaii’s Kilauea volcano. The flow from fissure 8 extends from the Leilani Estates to the Pacific Ocean — with main ocean entry points near Ahalanui.
The imagery, from the Advanced Spaceborne Thermal Emission and Reflection (ASTER) radiometer instrument on NASA’s Terra satellite, was taken on Wednesday, July 25th. Vegetation is shown in red, and clouds are white.

Pasadena, CA – The eruption of Kilauea Volcano on the island of Hawaii triggered a number of gas- and lava-oozing fissures in the East Riff Zone of the volcano. The fissures and high levels of sulfur dioxide gas prompted evacuations in the area.
Images taken from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) onboard NASA’s Terra satellite picked up these new fissures.
In the first image, the red areas are vegetation, and the black and gray areas are old lava flows.
NASA’s Spitzer Space Telescope data shows Super Earth 55 Cancri e could have an Atmosphere similar to Earth’s
Written by Elizabeth Landau
Pasadena, CA – Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides.
Based on a 2016 study using data from NASA’s Spitzer Space Telescope, scientists speculated that lava would flow freely in lakes on the starlit side and become hardened on the face of perpetual darkness. The lava on the dayside would reflect radiation from the star, contributing to the overall observed temperature of the planet.

Pasadena, CA – One of our planet’s few exposed lava lakes is changing, and artificial intelligence is helping NASA understand how.
On January 21st, a fissure opened at the top of Ethiopia’s Erta Ale volcano — one of the few in the world with an active lava lake in its caldera. Volcanologists sent out requests for NASA’s Earth Observing 1 (EO-1) spacecraft to image the eruption, which was large enough to begin reshaping the volcano’s summit.
As it turned out, that spacecraft was already busy collecting data of the lava lake.

Greenbelt, MD – New NASA research reveals that the giant Martian volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity.
The last volcanic activity there ceased about 50 million years ago — around the time of Earth’s Cretaceous-Paleogene extinction, when large numbers of our planet’s plant and animal species (including dinosaurs) went extinct.

Pasadena, CA – Mt. Erebus is at the end of our world — and offers a portal to another.
It’s our planet’s southernmost active volcano, reaching 12,448 feet (3,794 meters) above Ross Island in Antarctica. Temperatures at the surface are well below freezing most of the year, but that doesn’t stop visits from scientists: Erebus is also one of the few volcanoes in the world with an exposed lava lake. You can peer over the lip of its main crater and stare straight into it.
It’s also a good stand-in for a frozen alien world, the kind NASA wants to send robots to someday.
NASA’s Lunar Reconnaissance Orbiter helps researchers discover Volcanoes on the Moon younger than expected
Written by Tony Phillips
Washington, D.C. – Back in 1971, Apollo 15 astronauts orbiting the Moon photographed something very odd. Researchers called it “Ina,” and it looked like the aftermath of a volcanic eruption.
There’s nothing odd about volcanoes on the Moon, per se. Much of the Moon’s ancient surface is covered with hardened lava. The main features of the “Man in the Moon,” in fact, are old basaltic flows deposited billions of years ago when the Moon was wracked by violent eruptions. The strange thing about Ina was its age.
