Keeping a Steady Eye on Sea Level Change From Space

The Sentinel-6/Jason-CS satellite mission will add to a long-term sea level dataset that's become the gold standard for climate studies from orbit.

Coastal areas around the world - such as the Zambezi River Delta shown in a Landsat 8 satellite image - are contending with the consequences of a warming planet including droughts and floods, in addition to changing sea levels.

Shock waves from stellar explosions take preferential direction

Supernovae and magnetic fields in the laboratory In a paper (DOI: 10.3847/1538-4357/ab92a4) published in the Astrophysical Journal, a team led by researchers at École Polytechnique have paved the way to unravelling the mystery as to why many supernova remnants that we observe from Earth are axisymmetric (elongated along one axis) rather than spherical.

Portable system boosts laser precision, at room temperature

“Light squeezer” reduces quantum noise in lasers, could enhance quantum computing and gravitational-wave detection.

An MIT-designed miniature “squeezer” reduces quantum noise in lasers at room temperature. The marble-sized system could enable better laser precision for quantum computing and gravitational-wave detection. This illustration shows an artist’s interpretation of the system.

Sulphur dioxide concentrations drop over India during COVID-19

Concentrations of sulphur dioxide in polluted areas in India have decreased by around 40% between April 2019 and April 2020. Using data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, scientists have produced new maps which show the drop in concentrations across the country in times of COVID-19.

TESS mission discovers massive ice giant

Neptune-sized planet may be remnant core of a much larger planet.

MIT-Tess-Planets-01_0_0.jpg
In our solar system, the “ice giants” Neptune and Uranus are far less dense than rocky Venus and Earth. But astrophysicists on NASA’s TESS mission have now found an exoplanet, TOI-849b, that appears to be 40 times more massive than Earth, yet just as dense. This illustration depicts the exoplanet, UCF-1.01. Like TOI-849b, this exoplanet also orbits close to a star and is like “hot Neptune."

Radar Points to Moon Being More Metallic Than Researchers Thought

This image based on data from NASA’s Lunar Reconnaissance Orbiter spacecraft shows the face of the Moon we see from Earth. The more we learn about our nearest neighbor, the more we begin to understand the Moon as a dynamic place with useful resources that could one day even support human presence.
