The European Southern Observatory’s VISTA telescope has collected more than 500 terabytes of data on our galaxy......»»
Image: An aurora in another light
The Visible Infrared Imaging Radiometer Suite sensor on the NOAA-NASA Suomi NPP satellite captured this image of the aurora borealis, or northern lights, over western Canada at 3:23 a.m. MST (5:23 a.m. EST) on November 5, 2023......»»
Scientists make non-toxic quantum dots for shortwave infrared image sensors

Scientists develop high-power optic fiber laser to power nano satellites
The use of lasers in space is a reality. Even though radio waves have been the backbone of space communications for ages, the demand to convey more data, in a faster way, made these lighter, more flexible, and more secure infrared rays (invisible to.....»»
Research team uses water as a nonlinear medium for ultra-broadband white laser
Scientists are making significant strides in the development of ultrabroadband white laser sources, covering a wide spectrum from ultraviolet to far infrared. These lasers find applications in diverse fields such as large-scale imaging, femto-chemist.....»»
Gravitational waves could show us the first minute of the universe
Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves and infrared to gamma rays. There is a problem with studying the universe through the electromagneti.....»»
Daily Telescope: Life on Earth, and maybe in the heavens above, in a single photo
It is fun to contemplate all of the life on display in this image. Enlarge / The Milky Way over the sea. (credit: Alfonso Tamés) Welcome to the Daily Telescope. There is a little too much darkness in this world and.....»»
New instrument to capture stardust as part of NASA mission
Scientists and engineers at the CU Boulder will soon take part in an effort to collect a bit of stardust—the tiny bits of matter that flow through the Milky Way Galaxy and were once the initial building blocks of our solar system......»»
"Stellar paternity tests" match orphaned stars to their Milky Way origins
In the chaotic environment of open star clusters, strong gravitational interactions between bodies can launch individual stars far outside the cluster, even outside our galaxy, the Milky Way. Now, for the first time researchers have mapped several of.....»»
Research team reports observing vibrational spectra of a single protein with infrared nanospectroscopy
An interdisciplinary research team, led by Assistant Prof. Jun Nishida and Associate Prof. Takashi Kumagai at the Institute for Molecular Science, has successfully observed vibrational spectra of single proteins, consisting of approximately 500 amino.....»»
Webb finds signs of possible aurorae on isolated brown dwarf
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discov.....»»
Daily Telescope: The Milky Way above one of my favorite places on Earth
This photo is really not that much different than what you'll see with the naked eye. Enlarge / The Milky Way above Mauna Kea. (credit: Samuel Muller) Welcome to the Daily Telescope. There is a little too much darknes.....»»
A colossal star erupts: Examining one of the largest stars in the Milky Way as it fades from view
Astronomers from Georgia State University's CHARA Array have captured the first close-up images of a massive star known as RW Cephei that recently experienced a strange fading event. The images are providing new clues about what's happening around th.....»»
Non-toxic quantum dots pave the way towards CMOS shortwave infrared image sensors for consumer electronics
Invisible to our eyes, shortwave infrared (SWIR) light can enable unprecedented reliability, function and performance in high-volume, computer vision first applications in service robotics, automotive and consumer electronics markets......»»
Globular cluster VVV CL002 is falling down to the galactic center, study finds
Using the Magellan Clay telescope in Chile, astronomers have performed high-resolution spectroscopic observations of a galactic globular cluster known as VVV CL002. They found that the cluster is falling down to the Milky Way's center. The discovery.....»»
New high-speed video system uses sensors, infrared illumination to track insects in large wild areas
Our ability to learn more about insect behavior—which affects ecology, health, and economy on a global scale—depends largely on suitable recording technology. But until now, these tools have been considerably limited......»»
The early universe was surprisingly filled with spiral galaxies, research suggests
If we could travel far beyond our galaxy, and look back upon the Milky Way, it would be a glorious sight. Luminous spirals stretching from a central core, with dust and nebulae scattered along the spiral edges. When you think about a galaxy, you prob.....»»
JWST sets a new record, sees newly forming stars in the Triangulum galaxy
Our Milky Way bristles with giant molecular clouds birthing stars. Based on what we see here, astronomers assume that the process of star creation also goes on similarly in other galaxies. It makes sense since their stars have to form somehow. Now, t.....»»
Meet the infrared telescopes that paved the way for NASA"s Webb
The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite......»»
In mighty Atlantic Ocean, ecosystem wonders and threats lie below the surface
Scientists from numerous countries are joining forces to tackle risks to life in the world's second-largest ocean......»»
Astronomers detect seismic ripples in ancient galactic disk
A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe......»»
