How life on Mars might be 'sniffed out' by BILI
...planets. BILI works on a similar principle to other types of remote sensing instruments such as radar, but instead of using radio waves to probe its environment, BILI is a fluorescence-based lidar, meaning that it uses light to detect and analyse the...

Milky Way dark matter still as elusive as ever
... of pulsars – incredibly dense, rapidly spinning cores of collapsed stars that emit light predominantly in gamma-rays and radio waves. "Considering that about 70 percent of all point sources in the Milky Way are pulsars, they were the...

Storm-plagued exoplanet revealed in detail with GRAVITY
... (VLTI) and represents a huge step forward in observing objects in visible light. Interferometry works by combining light, be it radio waves or visible light, from two or more telescopes to act as one unit. The distance between two telescopes, also...

Earliest known galaxy merger detected by ALMA
... that B14-65666 is a pair of merging galaxies in the earliest era of the Universe," explains Hashimoto. "Detection of radio waves from three components in such a distant object clearly demonstrates ALMA's high capability to investigate the distant...

Space missions to watch out for in 2022
... a new method of communication by laser. This technology demonstration encodes its messages on photons – particles of light – instead of radio waves, which gives it the potential to transmit far more data back to Earth in a given amount of time than...

First-ever photo proof of powerful jet emerging from colliding galaxies
... than our sun will produce in its entire lifetime. That energy is in the form of radiation, such as intense radio waves, X-rays, and gamma-rays. "Jets are the best accelerators in the universe -- far better than the...
