Super Weapons

Our history has been one of inventing ever more devastating and unstoppable weapons, and yet they may pale in comparison to those made to wreck whole galaxies or tear asunder reality itself.

Three Stars, One Strange Disk! The Mind-Boggling Planet-Forming Revolution!

Key Takeaways:

Within this system, two young stars engage in an intimate celestial waltz, while a third star pirouettes around the pair. Enveloping all three stars is a fragmented disk of dust and gas, a cosmic canvas where future planets may take shape. This disk, unlike the one that gave rise to our solar system’s planets, comprises three loops, each with its unique contortions — a middle ring distinctly warped, and an inner ring playfully askew in relation to its companions.

Birch Planets: Galaxy-Sized Worlds

So called Dyson megaphere.


Birch Planets are enormous hypothetical Megastructures which would have more living area than every planet in our galaxy combined, and are even larger than Dyson Spheres.

Mega Earths

A look at creating artificial planets, ones vastly bigger than Earth, or potentially even an entire solar system.

Dracula’s Chivito: New Protoplanetary Disk discovered with Pan-STARRS

A protoplanetary disk is a disk of dense gas and dust, orbiting a newly formed star. It is assumed that planets are born by the gradual accumulation of material in such a structure, therefore discoveries and studies of protoplanetary disks are essential for improving our understanding of planetary formation processes.

Now, a team of astronomers led by Ciprian T. Berghea of the U.S. Naval Observatory (USNO) in Washington, DC, has discovered a new disk of this type that is associated with an infrared source known as IRAS 23077+6707. The finding was made by inspecting the Pan-STARRS data while working on a variability study of active galactic nuclei (AGN) candidates.
