In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet. Mars scientists have been anticipating epic solar storms ever since the Sun entered a period of peak activity earlier this year called solar maximum. Over the past month, NASA’s Mars rovers and orbiters have provided...
The data in this image used a narrow-band filter that allowed H-alpha emission through to the telescope’s detectors. The particular filter, called F657N (F for filter, N for narrow, and 657 for the wavelength in nanometers) or the H-alpha filter, lets through light very close to the 656.46 nanometer H-alpha line’s wavelength. It reveals pinkish star-forming regions...
The image is from an observation program dedicated to the study of dwarf galaxies in the Virgo cluster that is searching for the visible light emissions from sources of X-rays in these galaxies. X-rays are often emitted by accretion discs, where material that is drawn into a compact object by gravity crashes together and forms a hot, glowing disc. The compact object...
Astronomers have discovered enormous circular radio features of unknown origin around some galaxies. Now, new observations of one dubbed the Cloverleaf suggest it was created by clashing groups of galaxies. Studying these structures, collectively called ORCs (odd radio circles), in a different kind of light offered scientists a chance to probe everything from...
This Dec. 21, 2002, artist’s concept of NASA’s Galaxy Evolution Explorer imagines what the space telescope would look like during its mission. Launched April 28, 2003, it studied the shape, brightness, size and distance of galaxies across 10 billion years of cosmic history. By observing ultraviolet wavelengths, the telescope measured the history of star formation in...
We’re on the edge of our seats waiting for the solar eclipse. We hope you have your solar eclipse glasses and your popcorn ready for this out-of-this-world event. Of course, we wouldn’t be able to watch this without the tremendous research and innovations of stellar women in STEM. Today we’re shining a much-needed light on scientists and inventors who paved the way...

With tears in her eyes and a lump in her throat, Michelle explained to us what a typical night of homelessness looks likes for a woman. “A woman clutches her backpack to her chest and stands under a streetlight” She is terrified of the dangers that come with darkness, keenly aware of her vulnerability as a woman on the street. The streetlight casts a dim glow of...
Three newly released publications explore Native knowledge and practices in addressing climate change and environmental justice LONGMONT, Colorado (November 30, 2023) – First Nations Development Institute (First Nations) today announced the publication of three reports aimed to elevate community stories of adaptation in the face of environmental injustice. These...
