Gabekile – Southern Indian Ocean

Winds outside of Tropical Storm Gabekile are ripping the storm apart.

Hubble Embraces Spiral With Open Arms

The spiral galaxy NGC 2008 sits center stage, its ghostly spiral arms spreading out toward us, in this image captured by Hubble.

Pine Island Glacier’s Newest Iceberg

Iceberg B-49 calved from the Antarctic glacier in February 2020.

Climate Change Could Trigger More Landslides in High Mountain Asia

More frequent and intense rainfall events due to climate change could cause more landslides in the High Mountain Asia region of China, Tibet and Nepal, according to the first quantitative study of the link between precipitation and landslides in the region.

Making Waves in the Andaman Sea

When tides, currents, and gravity move water masses over seafloor features, they can create wave actions within the ocean.

Uesi – Southern Pacific Ocean

NASA analyzed Tropical Storm Uesi’s rainfall and found moderate to heavy rainfall around the storm’s center and in a large band of thunderstorms south of the center.

Moisture Pummels the Pacific Northwest

Following an exceptionally wet January, an atmospheric river carried even more moisture into the region in February.

Hubble Captures Grand Spiral

Eye-catching NGC 5364 is known as a grand design spiral galaxy — a descriptive name deserved by only one-tenth of spirals. They are characterized by their prominent, well-defined arms, which circle outward from a clear core. Despite being classified in this way, NGC 5364 is far from perfect.

Damien – Southern Indian Ocean

The low-pressure area that formed off Australia’s Kimberley coast and lingered there for a couple of days has moved west and developed into Tropical Cyclone Damien off the Pilbara coastline.

Thwaites Glacier Transformed

The amount of ice flowing from the Antarctic glacier has doubled in the span of three decades, and scientists think it could undergo even more dramatic changes in the near future.

Arctic Ice Melt Is Changing Ocean Currents

Using 12 years of satellite data, NASA scientists have measured how the influx of cold, fresh water is affecting the Beaufort Gyre, a major Arctic current.

Francisco – Southern Indian Ocean

Shortly after Tropical Cyclone Francisco formed on Feb. 5 in the Southern Indian Ocean, NASA’s Aqua satellite provided a visible image of the storm.

NASA’s Webb Will Seek Atmospheres around Potentially Habitable Exoplanets

More than one team of astronomers will study the TRAPPIST-1 system with Webb. They plan to use a variety of instruments and observing modes to tease out as many details as they can for each planet in the system.

Winter Flooding on the Mississippi

Persistent rains and saturated soils across the watershed swelled the river to its banks and occasionally onto floodplains.

Australia's Orroral Valley Fire Consumes Over 155,000 Acres in a Week

NASA's Terra satellite saw yet another fire, known as the Orroral Valley Fire, break out in the Canberra region of Australia, specifically in and around the ​Namadgi National Park.

Australian Smoke Plume Sets Records

Potent wildfires sent one of the largest plumes of smoke higher into the stratosphere than certain satellites have ever observed.

Eddy Extravaganza off the Italian Coast

Natural-color satellite images can capture art-like beauty when sediments trace water currents and eddies; other kinds of data can make that art intersect with scientific understanding.

Hubble Spies Bar, Baby Stars

​The galaxy depicted in this Hubble image is a barred spiral galaxy known as NGC 7541, in the constellation of Pisces (the Fishes). NGC 7541 is actually observed to have a higher-than-usual star formation rate, adding weight to the theory that spiral bars act as stellar nurseries.

NASA Catches Massive Smoke Plume from New South Wales Fires

Huge clouds of smoke spilled off the southeastern coast of Australia in this NASA Terra satellite image taken with the MODIS instrument (Moderate Resolution Imaging Spectroradiometer) on Jan. 31, 2020

Flood Waters Overwhelm Northern Madagascar

Torrential rains from several tropical disturbances soaked Madagascar in late January 2020, causing widespread and deadly flooding in the northern reaches of the island.

World of Change: Global Temperatures

The average global temperature has increased by a little more than 1 degree Celsius since 1880. Two-thirds of the warming has occurred since 1975.

NASA, Partners Name Ocean Studying Satellite for Noted Earth Scientist

NASA and several partners announced Tuesday they have renamed a key ocean observation satellite launching this fall in honor of Earth scientist Michael Freilich.

12P – Southern Pacific Ocean

Tropical Cyclone 12P formed in the Southern Pacific Ocean on January 25 and two days later, NASA’s Aqua satellite observed the storm’s demise.

Esami – Southern Indian Ocean

Tropical Cyclone Esami formed in the Southern Indian Ocean and just three days later, visible imagery from NASA’s Aqua satellite confirmed the storm had dissipated.

Diane – Southern Indian Ocean

Tropical Cyclone Diane formed late on January 24 and by the next day it was reduced to a remnant low-pressure system in the Southern Indian Ocean.
