In 1894, with the help of William Pickering, Percival Lowell, a wealthy Bostonian, founded the Lowell Observatory in Flagstaff, Arizona. In 1906, convinced he could resolve the conundrum of Uranus’s orbit, he began an extensive project to search for a planet beyond Neptune, which he named Planet X, a name previously used by Gabriel Dallet. The X in the name represents an unknown and is pronounced as the letter, as opposed to the Roman numeral for 10 (at the time, and now, Planet X would be the ninth planet). — Wikipedia

NASA has selected a new space mission that will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy's planetary systems. […]
Kepler's final image
on February 12, 2019 at 1:25 pm
On October 30th, 2018, after nine years of faithful service, the Kepler Space Telescope was officially retired. With nearly 4000 candidates and 2,662 confirmed exoplanets to its credit, no other telescope has managed to teach us more about the worlds that exist beyond our solar system. In the coming years, multiple next-generation telescopes will be deployed that will attempt to build on the foundation Kepler built. […]
New findings could make mosquitos more...

She weighs less than one ten-thousandth of an ounce and her top speed is less than two miles per hour. Nonetheless, the female mosquito is one of the most dangerous animals on the planet. For as she flies from person to person, biting us to draw the blood she needs to lay her eggs, this tiny creature transmits microbes that sicken and kill millions of people every year. […]
Citizen scientists find new world with NASA...
on January 9, 2019 at 3:07 pm
Using data from NASA's Kepler space telescope, citizen scientists have discovered a planet roughly twice the size of Earth located within its star's habitable zone, the range of orbital distances where liquid water may exist on the planet's surface. The new world, known as K2-288Bb, could be rocky or could be a gas-rich planet similar to Neptune. Its size is rare among exoplanets—planets beyond our solar system. […]
Alien imposters: Planets with oxygen don't...
on December 17, 2018 at 3:57 pm
In their search for life in solar systems near and far, researchers have often accepted the presence of oxygen in a planet's atmosphere as the surest sign that life may be present there. A new Johns Hopkins study, however, recommends a reconsideration of that rule of thumb. […]
