One Earth satellite can see plankton that photosynthesize. The other measures water surface height. Together, their data reveals how sea life and the ocean

Scientists said Thursday they have taken the first ever close-up image of a star outside of the Milky Way, capturing a blurry shot of a dying behemoth 2,000 times bigger than the Sun.Roughly 160,000 light years from Earth, the star WOH G64 sits in the Large Magellanic Cloud, a satellite galaxy of ou...

Astronomers have observed Gliese 229 B with the GRAVITY interferometer and, separately, the CRIRES+ spectrograph at ESO's Very Large Telescope.

In a study published in Engineering, researchers from Nanjing University of Aeronautics and Astronautics and Zhejiang University have unveiled a pioneering approach to designing on-chip computational spectrometers, heralding a new era of high-performance and reliable integrated spectrometers. This innovative inverse-design methodology offers a dramatic leap forward in spectrometer technology, addressing…

Scientists used the CHARA Array atop Mount Wilson in California to resolve previously unknown features of the North Star.

Astronomers using the Center for High Angular Resolution Astronomy (CHARA) Array have observed Polaris, a member of a triple system and the nearest and brightest classical Cepheid star.

Scientists from the Department of Physical Chemistry at the Fritz Haber Institute of the Max Planck Society have made a significant discovery in the field of nanotechnology, as detailed in their latest publication in Advanced Materials. Their paper, titled "Spectroscopic and Interferometric Sum-Frequency Imaging of Strongly Coupled Phonon Polaritons in SiC Metasurfaces," introduces a novel microscopy method that…

Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser technology have further enhanced its capabilities. There are two main types of laser spectroscopy: frequency comb-based laser spectroscopy and tunable continuous-wave (CW) laser spectroscopy.

Scientists used quantum technology to achieve unbelievable precision in measuring Earth's rotation, revolutionizing our understanding of planetary movements.

Scientists found an unknown object emitting microwaves near the Milky Way's center. The object's unique characteristics don't fit known celestial categories.

Exciton-polariton lasers, renowned for their low-power operation, have long tantalized researchers with their promise for practical low-energy applications. However, until now, a clean measurement of the laser's linewidth, or spectral purity, has remained elusive.

Researchers at the University of California, Los Angeles (UCLA) have achieved a significant milestone in optical imaging technology. A new all-optical complex field imager has been developed, capable of capturing both amplitude and phase information of optical fields without the need for digital processing.

Astronomers will be alerted to gravitational waves faster than ever before as LIGO and other detectors "listen" to a universal symphony.

Space.com caught up with Bill Diamond, President and CEO of the SETI Institute for an exclusive, mind-stretching close-encounter discussion regarding the...

The solar-powered aircraft would soar at up to 190 MPH for up to 111 miles on a full charge—nearly 10,000 miles a year.

A prototype antenna for the new SKA telescope, to be located in South Africa and Australia, just made a big step forward with a 1st-light image! The post SKA telescope 1st light! Milky Way core and more first appeared on EarthSky.

LISA, the Laser Interferometer Space Antenna, has passed a major review: the entire concept—from the definition of the overall mission and operations to the space hardware to be built—stood up to the intense scrutiny of ESA's reviewers.

The origin of Earth and the solar system inspires scientists and the public alike. By studying the present state of our home planet and other objects in the solar system, researchers have developed a detailed picture of the conditions when they evolved from a disk made of dust and gas surrounding the infant sun some 4.5 billion years ago.
