2024 Total Eclipse: Where & When - NASA Science
Nov 21, 2024 · A map developed using data from a variety of NASA sources shows the total eclipse path as a dark band. Outside this path, purple lines indicate how much of the Sun will become covered by the Moon during the partial eclipse.
The Effects of Climate Change - Science@NASA
Oct 23, 2024 · Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, …
Planetary Systems - NASA Science
Oct 22, 2024 · Planetary Systems. Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock.
The Causes of Climate Change - Science@NASA
Oct 23, 2024 · Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO 2).This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO 2.To a lesser extent, clearing of land for agriculture, industry, and other ...
Webb Image Galleries - NASA Science
Mar 7, 2024 · Taken during instrument calibration, this image helped test Webb’s ability to dig up galactic “fossils.” Ancient galaxies are so far that as space expands, their light has stretched into infrared wavelengths — Webb’s specialty.
Bennu - NASA Science
Dec 17, 2024 · Asteroid Bennu was the target of NASA's first asteroid sample return mission, OSIRIS-REx. The spacecraft delivered a sample of Bennu to Earth on Sept. 24, 2023.
Comets - NASA Science
Dec 9, 2024 · Overview. Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
Milankovitch (Orbital) Cycles and Their Role in Earth’s Climate
Feb 27, 2020 · Obliquity – The angle Earth’s axis of rotation is tilted as it travels around the Sun is known as obliquity. Obliquity is why Earth has seasons. Over the last million years, it has varied between 22.1 and 24.5 degrees with respect to Earth’s orbital plane.
Phobos - NASA Science
Nov 3, 2024 · The m ost prominent feature on Phobos is Stickney Crater, which is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet’s moons in 1877. Stickney crater is about 6-miles (9.7 kilometers) wide, and takes up about half the moon’s surface. NASA Mars Global Surveyor took images of the crater, and it appears to be ...
