Puzzling new gas signatures found on Mars
... the surface, using the gases light signature (its spectra) which appears in the ultraviolet portion of the electromagnetic spectrum. The new results, taken by the sensitive Atmospheric Chemistry Suite (ACS) instrument on TGO, shows that it is now...

Future space applications and their regulatory needs
... orbital debris. The near-Earth orbital domain is severely polluted with debris. We are quickly running out of electromagnetic spectrum, which is a finite and limited resource that we must learn to manage better in the face of tremendous pressure...

Does the speed of light change with time?
... from us, the light it emits gets stretched, so the light is seen as ‘shifted’ towards the red part of the electromagnetic spectrum. The more distant an object, the more it will be redshifted. This unexplained discovery was awarded the 2011...

Deepest spectroscopic survey completed of the Hubble Ultra Deep Field
... Telescope. And since then, 13 instruments on eight telescopes have observed the field covering nearly the complete electromagnetic spectrum from X-ray to radio wavelengths. Despite the years of research already conducted into the HUDF, with the...

LISA gets green light from ESA
... for waves at a higher frequency than what LISA will detect. By detecting gravitational waves within a broader spectrum of the electromagnetic spectrum, it could help scientists to understand the Universe in a whole new way, and could give insights...
