An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. It is the first exoplanet – a planet outside of our solar system – discovered at the UA. Weighing in at 11 times Jupiter's mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b...

During its five-year primary mission, NASA's Fermi Gamma-ray Space Telescope has given astronomers an increasingly detailed portrait of the universe's most extraordinary phenomena, from giant black holes in the hearts of distant galaxies to thunderstorms on Earth.
Astronomers have developed a new type of camera that allows scientists to take sharper images of the night sky than ever before. The team has been developing this technology for more than 20 years at observatories in Arizona, most recently at the Large Binocular Telescope, or LBT, and has now deployed the latest version of these cameras in the high desert of Chile at the Magellan 6.5-meter telescope.
This intriguing new view of a spectacular stellar nursery, IC 2944, is being released to celebrate a milestone: 15 years of ESO’s Very Large Telescope. This image also shows a group of thick clouds of dust known as the Thackeray globules silhouetted against the pale pink glowing gas of the nebula.
NASA's Hubble Space Telescope has discovered a new moon orbiting the distant blue-green planet Neptune, the 14th known to be circling the giant planet. The moon, designated S/2004 N 1, is estimated to be no more than 12 miles across, making it the smallest known moon in the Neptunian system.
Santa Barbara, CA –– Hovering about 70 light-years from Earth –– that's "next door" by astronomical standards –– is a star astronomers call HD 97658, which is almost bright enough to see with the naked eye. But the real "star" is the planet HD 97658b, not much more than twice the Earth's diameter and a little less than eight times its mass. HD 97658b is a super-Earth, a class of planet for...
John Howell, a Professor of Physics at the University of Rochester, decided to tackle an unusual DIY project. With the help of his 14 year-old son, Benjamin, he built three simple, but surprisingly effective optical cloaking devices with inexpensive, off-the-shelf materials.
This 10x Confocal image of drosophila larval musculature and its innervating and synaptic connections was an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competion. It ws taken by Dr. Timothy James Mosca of the Stanford University Department of Biology in Standford, California.
A weevil with an extremely long snout was photographed by Chao Zhang of the Chinese Academy of Sciences in Beijing, China. The 4x image of reflected light was an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition.
This 21.2x photo of Hymenoptera: Eupelmidae (parasitic wasp) was taken using a reflected light technique by Nikola Rahme of Budapest, Hungary. The photo was an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competion.
Much like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of...
An interdisciplinary team of researchers has created the first digital cameras with designs that mimic those of ocular systems found in dragonflies, bees, praying mantises and other insects. This class of technology offers exceptionally wide-angle fields of view, with low aberrations, high acuity to motion, and nearly infinite depth of field.
Researchers have found a way to see synthetic nanostructures and molecules using a new type of super-resolution optical microscopy that does not require fluorescent dyes, representing a practical tool for biomedical and nanotechnology research. Super-resolution optical microscopy has opened a new window into the nanoscopic world
A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes the light to travel back to a detector. The technique, called time-of-flight (ToF), is already used in machine vision, navigation systems for autonomous vehicles, and other applications, but many current ToF...
Just as the power of the open-source design has driven down the cost of software to the point that it is accessible to most people, open-source hardware makes it possible to drive down the cost of doing experimental science and expand access to everyone. As part of this movement, a Michigan Technological University lab has introduced a library of open-source, 3-D-printable optics components in a...
A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films. The technique, called energy-momentum spectroscopy, enables researchers to look at the light emerging from a thin film and determine whether it is coming from emitters oriented along the plane of the film or from emitters oriented perpendicular to the film.
The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. This image is a digital combination of a ground-based image from the 0.9-meter telescope at Kitt Peak National Observatory and a space-based image from the Hubble Space Telescope.
The Hubble Space Telescope captured a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of this frame
