the researchers worked out the spread of the masses for more than 3,500 microlensing events

The UV radiation rates emanating from the host star in the TRAPPIST-1 system are large enough to have caused the planets to have hemorrhaged large amounts of water over time. The inner planets of the system, TRAPPIST-1b and -TRAPPIST-1c, could have lost more than 20 times the amount of water contained in Earth’s oceans over the course of 8 billion years.

these planets are so close that some scientists think microbes could potentially hop from planet to planet and colonize the system outright.

In 1671, Giovanni Cassini gazed through a telescope at Saturn, and discovered a number of incredible wonders: the famed gap in its rings, detailed band structures in its atmosphere, and a number of moons.

One of those worlds, TRAPPIST-1e, might be the vacation hotspot of the future.
