Este mapa de la Tierra en 2023 muestra las anomalías de la temperatura global de la superficie, es decir, cuánto más cálida o más fría estuvo cada región del planeta en comparación con el promedio del período de 1951 a 1980. Las temperaturas normales se muestran en blanco, las superiores a las normales en rojo y naranja, y las inferiores a las normales en azul. Una versión animada de este mapa muestra la evolución de las anomalías de la temperatura global a lo largo del tiempo, desde 1880.

This map of Earth in 2023 shows global surface temperature anomalies, or how much warmer or cooler each region of the planet was compared to the average from 1951 to 1980. Normal temperatures are shown in white, higher-than-normal temperatures in red and orange, and lower-than-normal temperatures in blue. An animated version of this map shows global temperature anomalies changing over time, dating back to 1880. NASA’s Scientific Visualization Studio Earth’s average surface temperature in 2023 was the warmest on record, according to an analysis by NASA. Global temperatures last year were around 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the average for NASA’s ba…

NASA/Joshua Stevens; USGS The Operational Land Imager-2 on Landsat 9 captured this image of Simsbury, Connecticut on September 15, 2022. Martin Luther King Jr. and other students from Morehouse College worked summers on a tobacco farm, Meadowood, in Simsbury in 1944 and 1947 to earn money for tuition. King’s time in Connecticut impacted his outlook and trajectory as a minister and civil rights activist, according to King scholars.

In space since their launch on Nov. 16, 1973, Skylab 4 astronauts Gerald P. Carr, Edward G. Gibson, and William R. Pogue began the new year of 1974 roughly halfway through their planned 84-day mission. By the end of January, the three rookies held the records for the longest single space flight and the most cumulative time spent in space. Mission managers monitored the station’s and the astronauts’ health and weekly concurred with extending the mission to its full duration as the astronauts accomplished a record number of science observations of the Sun, the Earth, Comet Kohoutek, and themselves. Carr and Gibson completed the final Skylab spacewalk to bring inside externa…

NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, seen here in an artist’s concept, is scheduled to launch no earlier than Feb. 6, 2024, to study Earth’s oceans, atmosphere, and climate. NASA/Conceptual Image Laboratory NASA will host a media teleconference at 12 p.m. EST, Wednesday, Jan. 17, to discuss the upcoming launch and science objectives of the agency’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission. Once in orbit above Earth, the satellite will shed light on the impact of tiny things – microscopic life in water and microscopic particles in the air. With new global insights, PACE will help answer questions about how our oceans and at…

6 Min Read NASA’s PACE To Investigate Oceans, Atmospheres in Changing Climate Earth is complex – the atmosphere, ocean, land, and each small interwoven facet of those systems is a puzzle piece that connects and fills out the full picture. With a changing climate, the puzzle is becoming more complex – and important – to understand. Credits: NASA / Ryan Fitzgibbons and Emme Watkins Earth’s oceans and atmosphere are changing as the planet warms. Some ocean waters become greener as more microscopic organisms bloom. In the atmosphere, dust storms born on one continent affect the air quality of another, while smoke from massiv…

NASA/Brandon Torres NASA astronaut Nicole Mann and U.S. Representative Zoe Lofgren talk with students and families at Youth Alliance, a community organization in Hollister, California, on Jan. 5. Mann, who was born in another small California community, spoke about her parents’ work as an auto mechanic and a manicurist and her own path to becoming a colonel in the U.S. Marine Corps. Later, she said, becoming the first indigenous woman from NASA to go to space helped her connect with people of other indigenous communities. Mann is registered with the Wailacki of the Round Valley Indian Tribes. Lofgren, the ranking member of the House Science, Space, and Technol…

5 min read NASA Scientists Discover a Novel Galactic ‘Fossil’ Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies. The X-rays outline giant clouds of cold gas in the nearby spiral galaxy NGC 4945. The gas appears to have blasted through the galaxy after its central supermassive black hole erupted some 5 million years ago. Some 5 million years ago, a black hole eruption in the galaxy NGC 4945 set off a star-formation frenzy and shot a vast cloud of gas into intergalactic space. Watch and learn how two X-ray telescopes revealed the story. Credit: NASA’s Goddard Space …

These images represent a sample of galaxy clusters that are part of the largest and most complete study to learn what triggers stars to form in the universe’s biggest galaxies. Clusters of galaxies are the largest objects in the universe held together by gravity and contain huge amounts of hot gas seen in X-rays. This research, made using Chandra and other telescopes, showed that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years. In these images, X-rays from Chandra are shown along with optical data from Hubble.X-ray: NASA/CXC/MIT/M. Calzadilla el al.; Optical: NASA/ESA/STScI; Image Processing: N…
