The Climate Events of 2020 Show How Excess Heat is Expressed on Earth

By most accounts, 2020 has been a rough year for the planet. It was the warmest year on record, just barely exceeding the record set in 2016 by less than a tenth of a degree according to NASA's analysis.

Researchers Rewind the Clock to Calculate Age and Site of Supernova Blast

Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA???s Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more accurate estimate of the location and time of the stellar detonation.

NASA Missions Unmask Magnetar Eruptions in Nearby Galaxies

On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on many NASA spacecraft. Scientists think the blast came from a supermagnetized stellar remnant located in a neighboring galaxy.

NASA Missions Help Investigate an "Old Faithful" Active Galaxy

Yellowstone National Park's Old Faithful geyser regularly blasts a jet of boiling water high in the air. Now, an international team of astronomers has discovered a cosmic equivalent, a distant galaxy that erupts roughly every 114 days.

NASA, NOAA to Announce 2020 Global Temperatures, Climate Conditions

Climate researchers from NASA and the National Oceanic and Atmospheric Administration (NOAA) will release their annual assessment of global temperatures and discuss the major climate trends of 2020 during a media teleconference at 1 p.m. EST Thursday, Jan. 14.

Roman Space Telescope Could Image 100 Hubble Ultra Deep Fields at Once

Some of the Hubble Space Telescope???s most iconic images are the deep fields, which unveil myriad galaxies across the universe, stretching back to within a few hundred million years of the big bang. The galaxy tapestry was uncovered by Hubble peering at a single patch of seemingly empty sky for hundreds of hours.

Hubble Views a Dazzling 'Fireworks Galaxy'

In the last century alone, NGC 6946 has experienced 10 observed supernovae, earning its nickname as the Fireworks Galaxy.

NASA Selects 4 Concepts for Small Missions to Study Universe's Secrets

NASA has chosen four small-scale astrophysics missions for further concept development in a new program called Pioneers.

The Long Decline of Arctic Sea Ice

Forty years of satellite data show that 2020 was just the latest in a decades-long decline of Arctic sea ice.

21 Ways to Celebrate the James Webb Space Telescope Launch in 2021

A new year brings hope, expectations, and promise. Related to the space science community, this year will also bring the much-anticipated launch of NASA???s James Webb Space Telescope.

NCCS-Enabled Science Advances Being Presented at Online AMS Annual Meeting

From more accurate hydrology forecasts to improved understanding of cyclone dynamics, science advances enabled by NASA Center for Climate Simulation (NCCS) resources are the subject of posters and virtual presentations at the 101st Annual Meeting of the American Meteorological Society (AMS 101), being held online January 10–15, 2021.
