One of the key elements of Earth’s climate system is the cryosphere – the many forms of ice found on Earth. Two new NASA missions use different technologies to help scientists better understand how frozen water is affecting our planet. Both will continue satellite data records that have greatly...

Earth recently experienced its largest annual increases in atmospheric carbon dioxide levels in at least 2,000 years. Data from NASA’s Orbiting Carbon Observatory-2 (OCO-2), which launched in 2014, are helping scientists understand why.
Earth, Sun, ISS

The Sun. It inspires songs, warms us, and grows our food. Life on land and in the oceans, the daily weather, and long-term climate patterns happen primarily because of energy we receive from our closest star. Even tiny variations in that energy can affect the workings of our planet’s atmosphere.... Read More

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our... Read More
Sky Watching, Meteor Showers
Aug 10, 2018
The fireworks show you watched in July most likely lasted 20 minutes. But in August, you can watch some celestial fireworks that will last hours and hours. This is the Perseid Meteor Shower. With a clear sky, observers will be able to see up to 60 meteors per hour at its peak.
Sun, Our Sun

People around the world look up and see our Sun every day. But through a space telescope, it looks nothing like it does from down on the ground. The surface dances with arches of solar material that reach up into the solar atmosphere – an environment of charged particles and magnetic fields unlike... Read More

Dark moonless nights for the summer Perseid Meteor Shower!
Jul 26, 2018
Go outside on a clear night, look up, and consider the following. Standing on Earth’s surface, we are part of the universe’s perpetual symphony of heavenly bodies rotating on their axes and revolving around one another in an intricate rhythm. As far as we know, we’re the only ones “listening” and... Read More

Oceans cover over 70% percent of Earth’s surface and profoundly influence our planet’s atmosphere, weather, and climate. However, uncovering the many secrets hidden beneath the ocean’s waves presents unique challenges for researchers, and requires specific technology to observe what humans can’t... Read More

New research from NASA’s Cassini spacecraft’s up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its rings and its moon Enceladus. The observations show for the first time that the waves travel on magnetic field lines connecting... Read More
Solar System, Mars, Planets of Our Solar System

July's night skies feature Mars opposition on the 27th, when Mars, Earth, and the Sun all line up, and Mars' closest approach to Earth since 2003 on the 31st. That means great Mars viewing, though the planet-wide Martian dust storm will make seeing details more difficult.

On February 15, 2013, a house-sized meteor entered into Earth’s atmosphere at over 40,000 mph and exploded 14 miles above Chelyabinsk, Russia. The blast – wielding more than 30 times the energy of the Hiroshima atom bomb – generated a shock wave that shattered windows and damaged buildings in... Read More
