While the unaided eye or binoculars can reveal much of the night sky, a telescope reveals so much more. Seeing Saturn’s rings or the Moon’s craters with your own eyes can be an “oh wow” moment. However, choosing the right telescope can be tricky. Some have lenses and some have mirrors. Some are moved by ...
We have long been fascinated with the idea of alien life. The earliest written record presenting the idea of “aliens” is seen in the satiric work of Assyrian writer Lucian of Samosata dated A.D. 200. In one novel, Lucian writes of a journey to the Moon and the bizarre life he imagines living there — ...
Pictures of the sky can show us cosmic wonders, while movies can bring them to life. Films from NASA’s NEOWISE space telescope reveal motion and change across the sky. Every six months, NASA’s Near-Earth Object Wide Field Infrared Survey Explorer, or NEOWISE, spacecraft completes one trip halfway around the Sun, taking images in all directions. Stitched ...
After mobilizing more than 300 scientists and engineers to establish a network of synchronized telescopes that form an Earth-sized virtual telescope, the international Event Horizon Telescope Collaboration snapped the first-ever images of supermassive black holes. The first image of the black hole at the center of the Messier 87 galaxy was released in 2019. The latest image, ...
More than half of the Sun-like star systems surveyed in the Milky Way harbor a mysterious type of planet unlike any in our own solar system that the James Webb Space Telescope will be able to shine some light on. Larger than Earth, smaller than Neptune, and orbiting closer to their stars than Mercury orbits ...
NASA’s Nancy Grace Roman Space Telescope team recently flight-certified all 24 of the detectors the mission needs. When NASA’s Roman Space Telescope launches in the mid-2020s, these devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky. These images will allow astronomers to explore ...
A team of astronomers at the University of Hawaiʻi at the Mānoa Institute for Astronomy (IfA) has produced the world’s largest three-dimensional astronomical imaging catalog of stars, galaxies, and quasars. The team used data from UH’s Panoramic Survey Telescope and Rapid Response System, or Pan-STARRS1 (PS1), on Haleakalā. The PS1 3π survey is the world’s ...
To understand the significance of the Spitzer Space Telescope in the understanding of our Solar System, think of what the steam engine meant for the industrial revolution. A national team of scientists published in the journal Nature Astronomy two papers that provide an inventory of the major discoveries made possible thanks to the Spitzer Space ...
Jupiter, named for the king of the ancient Roman gods, commands its own mini-version of our solar system of circling satellites; their movements convinced Galileo Galilei that Earth is not the center of the universe in the early 17th century. More than 400 years later, astronomers will use NASA’s James Webb Space Telescope to observe these ...
Resembling a space butterfly with its symmetrical structure, beautiful colors, and intricate patterns, this striking bubble of gas — known as NGC 2899 — appears to float and flutter across the sky in this new picture from ESO’s Very Large Telescope (VLT). This object has never before been imaged in such striking detail, with even ...
