NASA Returns to Arctic Studying Summer Sea Ice Melt
2024.07.26
What happens in the Arctic doesn’t stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth's rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost part of Earth have a large impact on the entire planet. That’s because the Arctic region acts ...
Hubble Images a Classic Spiral
2024.07.26
This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor. Several other galaxies, located relatively nearby to this one, are just beyond the frame of this image; one is close enough that gravitational interaction […]
NASA’s Fermi Finds New Feature in Brightest Gamma-Ray Burst Yet Seen Summary
2024.07.25
In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi Gamma-ray Space Telescope reveals a feature never seen before.
How NASA’s Roman Space Telescope Will Illuminate Cosmic Dawn
2024.07.25
Today, enormous stretches of space are crystal clear, but that wasn’t always the case. During its infancy, the universe was filled with a “fog” that made it opaque, cloaking the first stars and galaxies. NASA’s upcoming Nancy Grace Roman Space Telescope will probe the universe’s subsequent transition to the brilliant starscape we see today –– […]
NASA’s Webb Images Cold Exoplanet 12 Light-Years Away
2024.07.24
An international team of astronomers using NASA’s James Webb Space Telescope has directly imaged an exoplanet roughly 12 light-years from Earth. The planet, Epsilon Indi Ab, is one of the coldest exoplanets observed to date.
Watch Carbon Dioxide Move through Earth’s Atmosphere
2024.07.23
This global map shows concentrations of carbon dioxide as the gas moved through Earth’s atmosphere from January through March 2020, driven by wind patterns and atmospheric circulation
NASA Rocket Discovers New Energization Process in Upper Atmosphere
2024.07.22
When it comes to discoveries about our upper atmosphere, it pays to know your surroundings.
Fires Char the Siberian Arctic
2024.07.19
Large wildland fires are burning in the tundra of northern Russia.
Hubble Studies a Potential Galactic Merger
2024.07.19
This NASA/ESA Hubble Space Telescope image features the dwarf irregular galaxy NGC 5238, located 14.5 million light-years from Earth in the constellation Canes Venatici. Its unexciting, blob-like appearance seems to resemble an oversized star cluster more than a classic image of a galaxy. Its lackluster appearance belies its complicated structure, which is the subject of […]
Behind the Scenes of a NASA ‘Moonwalk’ in the Arizona Desert
2024.07.18
How NASA practices moonwalks on Earth, featuring astronauts Kate Rubins and Andre Douglas.
Beating the Heat in Pakistan
2024.07.17
Greening projects in Lahore could help cool the city as climate change and rapid urbanization intensifies the urban heat island effect.
Wildfire Scorches Eastern Oregon
2024.07.16
Fast-moving blazes tore through rangeland in the Pacific Northwest amid excessive heat.
NASA Celebrates 20 Years of Earth-Observing Aura Satellite
2024.07.16
From monitoring the hole in the ozone above the Antarctic to studying air quality around the entire planet, NASA’s Aura satellite has provided scientists with essential measurements during its two decades in orbit.
El Niño Exits
2024.07.15
The natural climate phenomenon contributed to upheavals in temperature and rainfall patterns across the globe.
NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World
2024.07.15
Near-infrared spectral analysis of terminator confirms differences in morning and evening atmosphere Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass […]
Hubble Measures the Distance to a Supernova
2024.07.12
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. […]
Extreme Heat Hammers U.S. Coasts
2024.07.12
As summer heat hit the western and eastern U.S. in July 2024, temperatures have been especially high in the Southwest.
Vivid Portrait of Interacting Galaxies Marks Webb’s Second Anniversary
2024.07.12
Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA’s James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a “parade” of discoveries by astronomers around the world.
NASA’s Hubble Traces Dark Matter in Dwarf Galaxy Using Stellar Motions
2024.07.11
The qualities and behavior of dark matter, the invisible “glue” of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it’s relevant to a galaxy’s evolution. While computer simulations suggest dark […]
A Smoky Summer in Amur
2024.07.11
Fires have been flaring periodically in this eastern region of Russia since May.
NASA’s Hubble Finds Strong Evidence for Intermediate-Mass Black Hole in Omega Centauri
2024.07.10
Most known black holes are either extremely massive, like the supermassive black holes that lie at the cores of large galaxies, or relatively lightweight, with a mass of under 100 times that of the Sun. Intermediate-mass black holes (IMBHs) are scarce, however, and are considered rare “missing links” in black hole evolution. Now, an international […]
Carriacou After Beryl

The Category 4 hurricane caused widespread damage to infrastructure and vegetation on the Grenadine island.
Beryl Becomes the First Major 2024 Atlantic Hurricane

Beryl became the earliest Category 4 hurricane on record in the Atlantic with sustained winds reported at 130 mph by the National Hurricane Center, surpassing Hurricane Dennis from the epic 2005 Atlantic hurricane season. Beryl also became historic as the strongest and easternmost hurricane and major hurricane in June in the Atlantic.
