NASA Simulation Suggests Volcanoes Might Warm Climate, Destroy Ozone Layer

NASA Simulation Suggests Volcanoes Might Warm Climate, Destroy Ozone Layer

A new NASA climate simulation suggests that extremely large volcanic eruptions called “flood basalt eruptions” might significantly warm Earth’s climate and devastate the ozone layer that shields life from the Sun’s ultraviolet radiation.

The result contradicts previous studies indicating these volcanoes cool the climate. It also suggests that while extensive flood-basalt eruptions on Mars and Venus may have helped warm their climates, they could have doomed the long-term habitability of these worlds by contributing to water loss.

Like Painting with Light | Gemini Observatory

Like Painting with Light | Gemini Observatory

Gemini North, one half of the international Gemini Observatory, a Program of NSF’s NOIRLab, uses a laser beam traveling through Earth’s atmosphere to adjust its adaptive optics. Like many large research telescopes today, Gemini North uses adaptive optics—bending its mirrors to compensate for atmospheric turbulence or “seeing”, which can blur the images of distant objects like stars and galaxies.

The laser beam, seen here as a pink-orange stripe on the sky, travels into the upper atmosphere where it creates a bright spot of light that provides a reference point for the telescope to follow, and correct for, the atmospheric turbulence. This long-exposure photograph shows the laser tracking its target near the zenith, appearing to paint the sky with light. The stars appear as trails as they revolve around the north celestial pole during the long exposure.

Strong Solar Flare Erupts from Sun | NASA's Solar Dynamics Observatory

Strong Solar Flare Erupts from Sun | NASA's Solar Dynamics Observatory

The Sun emitted a strong solar flare on April 30, 2022, peaking at 9:47 a.m. EDT. NASA’s Solar Dynamics Observatory (SDO), which watches the Sun constantly, captured an image of the event. This image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in red.

A red Sun, with a golden flare bursting from the top right.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.    

This flare is classified as an X-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. More info on how flares are classified can be found here.

Partial Solar Eclipse over Argentina

Partial Solar Eclipse over Argentina

Two days ago, parts of South America were treated to a partial solar eclipse—where the Moon blocked out part of the Sun. This is an image of the partially eclipsed Sun through clouds as it was setting over Patagonia, Argentina. In this tilted view, Earth is toward the right. During the eclipse, the Moon moved partly between Earth and the Sun. Although a visually impressive sight, the slight dimming of surroundings during this partial eclipse was less noticeable than dimming created by a thick cloud. In about two weeks, all of South America and part of North America will experience a total lunar eclipse—where the Earth moves completely between the Moon and the Sun. In about two years, a total solar eclipse will cross North America.

Hubble Sees Double in Spiral Galaxy M99

Hubble Sees Double in Spiral Galaxy M99

The magnificent spiral galaxy M99 fills the frame in this image from the NASA/ESA Hubble Space Telescope. M99—which lies roughly 42 million light-years from Earth in the constellation Coma Berenices—is a “grand design” spiral galaxy, so-called because of the well-defined, prominent spiral arms visible in this image. M99 was captured by Hubble’s Wide Field Camera 3 on two separate occasions, helping astronomers study two entirely different astronomical phenomena. 

The first set of observations aimed to explore a gap between two different varieties of cosmic explosions; novae and supernovae. Novae, which are caused by the interactions between white dwarfs and larger stars in binary systems, are far less bright than the supernovae which mark the catastrophically violent deaths of massive stars. However, current astronomical theories predict that sudden, fleeting events could occur that shine with brightnesses between those of novae and supernovae. Despite being described by astronomers as being shrouded in mystery and controversy, just such an event was observed in M99. Astronomers turned to Hubble’s keen vision to take a closer look and precisely locate the fading source.

The second set of observations were part of a large Hubble project which aims to chart the connections between young stars and the clouds of cold gas from which they form. Hubble inspected 38 nearby galaxies, identifying clusters of hot, young stars. These galaxies were also observed by the Atacama Large Millimeter/submillimeter Array (ALMA), a colossal radio telescope consisting of 66 individual dishes perched high in the Chilean Andes. The combination of Hubble’s observations of young stars and ALMA’s insight into clouds of cold gas will allow astronomers to delve into the details of star formation, and paves the way for future science with the NASA/ESA/CSA James Webb Space Telescope.

Purple Haze in the NGC 3627 Galaxy | European Southern Observatory

Purple Haze in the NGC 3627 Galaxy | European Southern Observatory

This Picture of the Week showcases the impressive NGC 3627 galaxy, also known as Messier 66, located approximately 31 million light-years from Earth in the constellation Leo. The image was taken with the Multi-Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope (VLT) in Chile. But why does it have these unusual colors?

This image is a combination of observations conducted in different wavelengths of light. However, rather than seeing the stars in this galaxy, as in more classical images, what this image displays is gas ionized by newly-born stars, with hydrogen, oxygen, and sulphur shown in red, blue and orange respectively. 

The image was taken as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) project, which is using telescopes operating across all wavelengths to make high-resolution observations of nearby galaxies. The goal of the project is to better understand what triggers, boosts or holds back the formation of new stars in different environments.

After collecting eight rock-core samples from its first science campaign and completing a record-breaking, 31-Martian-day (or sol) dash across about 3 miles (5 kilometers) of Mars, NASA’s Perseverance rover arrived at the doorstep of Jezero Crater’s ancient river delta April 13. Dubbed “Three Forks” by the Perseverance team (a reference to the spot where three route options to the delta merge), the location serves as the staging area for the rover’s second science expedition, the “Delta Front Campaign.”

“The delta at Jezero Crater promises to be a veritable geologic feast and one of the best locations on Mars to look for signs of past microscopic life,” said Thomas Zurbuchen, the associate administrator of NASA’s Science Mission Directorate in Washington. “The answers are out there—and Team Perseverance is ready to find them.”

The delta, a massive fan-shaped collection of rocks and sediment at the western edge of Jezero Crater, formed at the convergence of a Martian river and a crater lake billions of years ago. Its exploration tops the Perseverance science team’s wish list because all the fine-grained sediment deposited at its base long ago is the mission’s best bet for finding the preserved remnants of ancient microbial life.

The Jet Propulsion Laboratory (JPL), which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance and Curiosity rovers.

Mission Name: Mars 2020

Rover Name: Perseverance

Main Job: Seek signs of ancient life and collect samples of rock and regolith (broken rock and soil) for possible return to Earth.

Launch: July 30, 2020    

Landing: Feb. 18, 2021, Jezero Crater, Mars
