NASA’s Webb Probes an Extreme Starburst Galaxy

NASA’s Webb Probes an Extreme Starburst Galaxy

On the left is the starburst galaxy M82 as observed by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments as seen by Webb are the polycyclic aromatic hydrocarbon … Read more

That Starry Night Sky? It’s Full of Eclipses

That Starry Night Sky? It’s Full of Eclipses

And astronomers can, in a sense, “see” eclipses among other systems of planets orbiting their parent stars. In this case, the eclipse is a tiny drop in starlight as a planet, from our point of view, crosses the face of its star. That crossing, called a transit, can register on sensitive light sensors attached to … Read more

Cheers! NASA’s Webb Finds Ethanol, Other Icy Ingredients for Worlds

Cheers! NASA’s Webb Finds Ethanol, Other Icy Ingredients for Worlds

NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument) has identified a variety of complex organic molecules that are present in interstellar ices surrounding two protostars. These molecules, which are key ingredients for making potentially habitable worlds, include ethanol, formic acid, methane, and likely acetic acid, in the solid phase. The finding came from the study … Read more

NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists

NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists

The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. Goddard also conducts mission operations with Lockheed Martin … Read more

Peering Into the Tendrils of NGC 604 with NASA’s Webb

Peering Into the Tendrils of NGC 604 with NASA’s Webb

Webb’s view in mid-infrared wavelengths also illustrates a new perspective into the diverse and dynamic activity of this region. In the MIRI view of NGC 604, there are noticeably fewer stars. This is because hot stars emit much less light at these wavelengths, while the larger clouds of cooler gas and dust glow. Some of … Read more

What is Dark Energy? Inside our accelerating, expanding Universe – NASA Science

What is Dark Energy? Inside our accelerating, expanding Universe – NASA Science

Around this same time in history, astronomer Vesto Slipher observed spiral galaxies using his telescope’s spectrograph, a device that splits light into the colors that make it up, much like the way a prism splits light into a rainbow. He used the spectrograph, a relatively recent invention at the time, to see the different wavelengths … Read more

Discovery Alert: A ‘Super-Earth’ in the Habitable Zone – NASA Science

Discovery Alert: A ‘Super-Earth’ in the Habitable Zone – NASA Science

The recently discovered super-Earth, TOI-715 b, might be making its appearance at just the right time. Its parent star is a red dwarf, smaller and cooler than our Sun; a number of such stars are known to host small, rocky worlds. At the moment, they’re the best bet for finding habitable planets. These planets make … Read more

NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies – NASA Science

NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies – NASA Science

Spiral galaxy NGC 628 is 32 million light-years away in the constellation Pisces. Webb’s image of NGC 628 shows a densely populated face-on spiral galaxy anchored by its central region, which has a light blue haze that takes up about a quarter of the view. In this circular core is the brightest blue area. Within … Read more
