When staring out into the darkness of space, one of the most unsettling things we could see would be a pair of eyes staring right back. So, you can imagine astronomers’ shock when they chanced upon the Smiley Face Galaxies. These handsome cosmic chaps are the result of on Einstein Ring- the light from a galaxy in the background is being warped into an arc, by the gravity of two giant foreground elliptical galaxies which resemble eyes, surely making them the happiest places in the universe!

In 1998, two teams of scientists measured the universe's rate of expansion, expecting to find the gravity of the Cosmic Web bringing the universe into a collapse. But instead, they found that the universe's expansion appears to be accelerating- having expanded more in the latter half of its life. Both teams agreed upon the existence of a new type of energy field, known as Dark Energy, to drive this acceleration, and in doing so, they revived one of Einstein's long-rebuked ideas- the Cosmological Constant.

In 1999, the Hubble Telescope snapped its sharpest view yet of the Ring Nebula [M-57], a so-called "planetary nebulae". But is this object really the spherical bubble of gas we once thought? Hubble's gaze suggested otherwise. This is a deleted from my most recent video, Hubble's Greatest Discoveries.

The Sun... both the giver of life, and destroyer of worlds. Host of the eight planets, and incubator of Earth with its light and heat. Yet in spite of its brilliance, the true nature of the sun's power remains shrouded in mystery, with scientists unable to explain many of the processes playing out in its atmosphere. But in 2024, NASA will attain their closest glimpse of the sun so far, as they come just five million miles from its surface, diving into the stellar Nether Zone, to "touch" the sun itself.
