Researchers Combine Lasers and Terahertz Waves In Camera That Sees ‘Unseen’ Detail
A team of physicists at the University of Sussex has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation. Phys.Org reports: Led by Professor Marco Peccianti of the Emergent Photonics (EPic) Lab, Luana Olivieri, Dr. Juan S. Totero Gongora and a team of research students built a new type…
VLT sees surface of dim Betelgeuse
The European Southern Observatory’s Very Large Telescope is in northern Chile. Astronomers used it to capture the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The new images show how the apparent shape of this star is changing.

ESO telescope sees surface of dim Betelgeuse
Using ESO’s Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star’s surface show not only the fading red supergiant but also how its apparent shape is changing.

Camera provides view into Sun’s polar regions
The Solar Orbiter mission will use a U.S. Naval Research Laboratory-designed and -built heliospheric camera, known as SoloHI, to provide unique perspectives and unprecedented views of the Sun’s North and South poles. The spacecraft, a NASA and European Space Agency collaboration, launched aboard an Atlas V rocket at Cape Canaveral, Florida, Feb. 9.

The World’s Largest Solar Telescope Snaps Its First Photograph
sciencehabit quotes Science magazine: A new close-up of the turbulent boiling plasma of the solar surface is the debut image of the largest telescope ever built for staring at the Sun. Sporting a 4-meter-wide mirror — twice the size of any existing solar scope—and a vantage point 3000 meters up on the summit of Haleakala on the Hawaiian island of Maui…
Spitzer Space Telescope Turns Out the Lights
Long-time Slashdot reader Kreuzfeld writes: Thursday marks the final mission of NASA’s Spitzer Space Telescope. Conceived of as an infrared-optimized “Great Observatory,” Spitzer has spent the last 6002 days providing Earthlings with an unprecedented view into other galaxies, our own solar system, and (unexpected to its designers!) planets around other stars. But in its Earth-trailing solar orbit, Spitzer is now over…
Astronomers Capture the Highest-Resolution Photo of the Sun Ever Taken
Iwastheone shares a report from MIT Technology Review: Astronomers have just released the highest-resolution image of the sun. Taken by the Daniel K. Inouye Solar Telescope in Maui, it gives us an unprecedented view of our nearest star and brings us closer to solving several long-standing mysteries. The new image demonstrates the telescope’s potential power. It shows off a surface that’s…
