Exploring the extreme universe
... could send instruments above the Earth to get a view from space. Photons at the higher end of the electromagnetic spectrum, i.e. gamma-ray wavelengths that have an energy range above a Mega electron volt ( MeV ), are one million...

Planetary nebulae may hold clue in search of helium-3
... transition of ionised 3He (represented as 3He+) and this transition can only be observed in the radio portion of the electromagnetic spectrum at the rest frequency of 8.665 GHz. Unfortunately, this transition is not very common, making the line very...

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...

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...

High-resolution Earth observation data is changing the character of war
... the Operational Land Imager (OLI) on Landsat 8 which collects information in 11 narrow bands of wavelengths on the electromagnetic spectrum. False-colour imagery is used to provide additional scientific insights - the near infrared (band 5) in this...
