Lowell Observatory

An astronomer at Lowell Observatory used the Hubble Space Telescope to peer back in time at very distant galaxies. He found their position in space isn’t random; it’s influenced by other galaxies nearby. KNAU’s Melissa Sevigny reports on the new research.

Electronic billboards are restricted in most of Arizona to protect dark skies for astronomers. Now lawmakers have lifted the ban in a region of Mohave County. KNAU’s Melissa Sevigny reports.


More than 500-cities worldwide are participating in Saturday’s March For Science. Organizers say it’s a chance to bring awareness to the “very real role” science plays in our lives. Some are concerned the march will fuel the idea that the science community is a special interest group that politicizes its work. Others see it is a chance to celebrate the integrity of research and evidence. Todd Gonzalez is an educator at Lowell Observatory, and a speaker at tomorrow’s march in Flagstaff, one of seven Arizona cities participating. Gonzalez told KNAU’s Aaron Granillo he’s not worried about looking partisan.

A decade ago Flagstaff suffered a blow when Pluto was “demoted” to a dwarf planet. It was discovered at Lowell Observatory in Flagstaff in 1930 and is a source of pride for the city. But astronomers voted on the definition of a planet and Pluto didn’t make the cut. Now, planetary scientists say that definition is both overly complicated and incomplete.  They’ve suggested a different one. Melissa Sevigny from the Arizona Science Desk spoke with two Lowell scientists about the definition, Will Grundy and Gerard van Belle.

The public can now join the hunt for the elusive Planet Nine, a massive planet astronomers believe might be hidden beyond Neptune.
