The JWST is grabbing headlines and eyeballs as its mission gains momentum. The telescope recently imaged M74 (NGC 628) with its Mid-Infrared Instrument (MIRI.) Judy Schmidt, a well-known amateur astronomy image processor, has worked on the image to bring out more detail.Continue reading “Here’s M74 Like You’ve Never Seen it Before, Thanks to Judy Schmidt and JWST”
The Universe is full of massive galaxies like ours, but astronomers don’t fully understand how they grew and evolved. They know that the first galaxies formed at least as early as 670 million years after the Big Bang. They know that mergers play a role in the growth of galaxies. Astronomers also know that supermassive black holes are involved in the growth of galaxies, but they don’t know precisely how.
A new Hubble survey of galaxies should help astronomers figure some of this out.Continue reading “Hubble Finds a Bunch of Galaxies That Webb Should Check out”

We’re about to reach a milestone that many thought we would never reach. After years of wrangling, cost overruns, threats of cancellation, and lobbying by the science community, the James Webb Space Telescope is only weeks away from its first images.Continue reading “First Images From JWST are Coming on July 12th”
Direct images of exoplanets are rare and lack detail. Future observatories might change that, but for now, exoplanet images don’t tell researchers very much. They merely show the presence of the planets as blobs of light.
But a new study shows that only a few pixels can help us understand an exoplanet’s surface features.Continue reading “Just a Few Pixels Would let Astronomers Map Surface Features on an Exoplanet Like Oceans and Deserts”
In our age, we’ve grown accustomed to pictures of astronauts inside the International Space Station, as they float in zero-G and tend their science experiments. We’re even getting used to images of spacewalking astronauts. But this is something new.

Missions to Mars are expensive, even orbiters. They’re there to do science, not take pretty pictures. But sometimes Mars’ beauty is captured inadvertently, usually with some science mixed in.
That’s the case with this picture of star dunes captured by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.Continue reading “These are Star Dunes on Mars, Formed When the Wind Comes From Many Different Directions”
North Korea released some pictures they say come from their recent missile test. The missile they tested—the intermediate-range Hwasong-12—can reach the U.S. territory of Guam. According to most North Korea observers, the country hopes the tests will bring the U.S. back to the negotiating table.Continue reading “North Korea Releases Pictures of Earth They Say Were Taken From Space”
Those images showed everyone that what appears to be a tiny, empty part of the sky contains thousands of galaxies, some dating back to the Universe’s early days. Each of those galaxies can have hundreds of billions of stars. These early galaxies formed only a few hundred million years after the Big Bang. The images inspired awe in the human minds that took the time to understand them. And they’re part of history now.
The upcoming Nancy Grace Roman Space Telescope (NGRST) will capture its own version of those historical images but in wide-angle. To whet our appetites for the NGRST’s image, a group of astrophysicists have created a simulation to show us what it’ll look like.Continue reading “Nancy Grace Roman Telescope Will do its Own, Wide-Angle Version of the Hubble Deep Field”
The ESO has released some stunning new images of Orion’s Flame Nebula. They’re from a few years ago but are newly processed as part of the Orion cloud complex study. The images have led to discoveries in the often-observed Orion cloud complex.Continue reading “A New Image Reveals Orion’s Flame Nebula in Infrared”
The interplay of energy and matter creates beautiful sights. Here on Earth, we enjoy rainbows, auroras, and sunsets and sunrises. But out in space, nature creates extraordinarily dazzling structures called nebulae that can span hundreds of light-years. Nebulae are probably the most beautiful objects out there.
While searching for young stars and their circumstellar disks, Hubble captured a classic reflection nebula.Continue reading “This is a Classic Example of a Reflection Nebula, Where the Reflected Light From Young Hot Stars Illuminates a Protostellar Cloud of Gas and Dust”
