... at specific wavelengths. Collecting light from each star is very time consuming – it takes about an hour to collect enough photons of light for each star in order to scrutinise its spectra. Luckily the Anglo-Australian Telescope (AAT) at the...
.... To determine how the Moon formed, CubeX would use a technique called X-ray fluorescence, or XRF to capture “fluorescing” photons with a tiny X-ray optic and an onboard spectrometer. XRF works by detecting X-rays emitted from individual atoms...
... (3.6 million degrees Fahrenheit) and while other NASA telescopes such as Chandra can pick up these super hot photons, it can only do so in a small patch of sky at any one time. HaloSat on the other hand will look at the...
... to travel past Venus via nothing more than the momentum gained from the massless light particles (photons) bombarding the sail, which stream constantly from the Sun. The probe had no steering mechanism though...
... need to point its beam with sufficient accuracy and precision so that the target can receive as many photons as possible into the collector, another seemingly innocuous Earthly feature can cause problems; cloud cover. If just...
... has a temperature of 28 000 degrees Celsius (five times as hot as the Sun), in just 10 days. The high-energy photons crammed inside the dead star are gradually blowing away the planet's atmosphere and while most...
