Tuesday, January 7, 2025: New year, new milestone: A cosmic quirk of nature has allowed the James Webb Space Telescope (JWST) to capture images of 44 individual stars in a galaxy halfway across the observable universe — this region is so distant that astronomers once deemed identifying indiv...
"The ELT will allow us to zoom into specific regions with unprecedented detail, giving us a never-seen-before close-up view of individual stars that are currently forming there," Meingast said. The creation of the stellar nursery atlas is documented in a peer-reviewed paper published Thursday...
But even the largest individual objects are no match for cosmic collections of objects. The Solar System, as viewed on a logarithmic scale, highlights just how far away some of the objects are. The planets, the Kuiper belt, the Oort cloud, and the nearest star are all shown here, with ...

To produce detailed pictures of the moon’s surface, astrophotographers often record short video files with a planetary camera (or solar system camera). The best individual image frames are then extracted from the video and stacked. One of the many advantages of this method is the ability to...
Important Individual Stars The Sun –Classified G-2 yellow dwarf, our middle-aged host star warms earth from 93 million miles away up to 10,000 degrees Fahrenheit. Polaris– Earth’s current North Star resides 431 light years distant in the Little Dipper Ursa Minor constellation. Its aligned ...
of the container so it shows one kind of surface on the top and quite a different kind where it was resting on other semi-molten blobs underneath. Contrast the relatively dull broken crystal surfaces of this 99.5% pure lump with the much shinier, crisper crystals of the 99.99+% lump above...
Some amateurs spend their time capturing the Moon and planets, some focus on wide-field vistas, and others concentrate on detailed portraits of individual deep sky objects. Amateurs engaged in these different branches of astrophotography don't just shoot different objects; they typically use very ...
A Chandrayaan-1 Moon Mineralogy Mapper infrared image (left) of a lunar farside crater indicates the presence of water (shown by blue tint at right). The "water" is not liquid, but individual molecules stuck to the surface, and may be simply due to hydrogen atoms from the solar wind inte...
Physicists in Switzerland and the Netherlands unveiled a new form of atomic force microscopy (AFM) capable of identifying individual atoms within a molecule. In a paper published in August they revealed this image of a pentacene molecule where the hexagonal shapes of the five carbon rings are all...
