When we look up at the night sky with the unaided eye, we see stars that are up to about 1000 light years away, depending on their brightness. We also see objects which are much closer, in our celestial backyard so to speak, which only reflect light from the sun …
What Would Happen if you fell into a Black Hole?
Imagine we are at some point in future on a mission to study black holes and orbiting near the photon sphere, an area just far enough away where photons of light travel fast enough to settle into an orbit and don’t get pulled into the event horizon. However, through no …
How is NASA Hearing Stars?
This garden universe vibrates completeSome, we get a sound so sweetVibrations reach on up to become lightAnd then through gamma, out of sightBetween the eyes and ears there lieThe sounds of colour and the light of a sighAnd to hear the sun, what a thing to believeBut it’s all around …
Proving the Big Bang and beyond with Planck
Ever since we came up with the theory of the big bang, we been looking for evidence to back it up. Put simply, The big bang theory is the leading explanation of how the universe came to be, from an infinitely small but equally high density and temperature point that …
ESA’s million-year time machine
This is not a photo of the Milkyway or an artist’s impression, this a map made up of approximately 1.8 billion data points collected by the Gaia satellite, each one not just representing a star but also comets, asteroids and other astronomical objects in the Milkyway and beyond. But its …
How could anyone believe the moon is hollow?
As conspiracy theories go, believing that the Moon is hollow is up there with thinking its made out of cheese. The Hollow Moon hypothesis suggests that the moon might be the product of an alien civilisation and could be a giant spacecraft or space station. However, as with all the …
How are we searching for Extra Terrestrial messages ?
We have been searching for signs of extra-terrestrial life for over 100 years, and so far, we have found no evidence of anything beyond our planet. Out of all the billions of stars just in our own galaxy, the Milkyway, with all the billions of associated planets, let alone the …
How Long Could You Survive in a Black Hole?
Imagine we are at some point in future on a mission to study black holes and orbiting near the photon sphere, an area just far enough away where photons of light travel fast enough to settle into an orbit and don’t get pulled into the event horizon. However, through no …
How Do We Know What the Milky Way Really Looks Like?
This is what our galaxy looks like and where we are in it, or so we are told because this is a side on view from what would be about a million light years away. Now clearly we have a problem here because the farthest manmade object capable of taking …
How NASA’s New Spacesuit Could Stall the 2024 Artemis Moon Landings.
They are as important as the rockets the astronauts fly in and a miracle of materials and clothing engineering. Without them, we would not have been able to walk on the moon but the current generation of spacesuit’s or Extravehicular Mobility Units which were designed in the late 1970s are …
