Just before sunrise this morning our automated all sky camera captured the aurora borealis over Providence, Rhode Island. Also visible is the International Space Station and the planets Mars and Saturn.
On March 6 we received reports that the aurora borealis was observed in New England just before sunrise. One of our visitors described seeing the northern lights from a rest area on Route 495 near Boston. Our automated all sky camera was running the entire night and captured the view.

"The timepiece that we use, the Earth, is not as accurate as we need it to be in modern society"
Leap years, like the one this year, keep the calendar on track. Try for yourself: can you keep Jan. 1 close to the start of the solar year?

A "new star" appeared in the constellation Perseus in 1901 and was observed by Prof. Winslow Upton at Ladd Observatory. A young H.P. Lovecraft also saw the cosmic sight which inspired him to include the nova in his weird tales of horror. Discover the story and history of Nova Persei 1901 through the collections of the Brown University Library and Ladd Observatory.

Prof. Ian Dell'Antonio will discuss the modern astrophysics of novae, Observatory Curator Michael Umbricht will describe the historic observations and present a demonstration using the astronomical spectroscope used by Upton, and Curator Holly Snyder will display rare items from the history of science special collections of the John Hay Library.

This event is part of the Ladd Observatory 125th anniversary and is sponsored by the Department of Physics and Brown University Library.

There are sometimes news reports of a “close approach” where an asteroids passes particularly near the Earth. An asteroid called 2013 TX68 will pass the Earth on March 8, 2016. It is estimated to be 100 feet in diameter.

Objects passing near the Earth happen more frequently than one might expect. A number of these approaches will happen this month.

Learn about Near-Earth Object close approaches.
A Near-Earth Object is an asteroid or comet that is in an orbit that sometimes brings it close to the Earth. The largest of these are known as Potentially Hazardous Objects as they could cause significant damage if they impacted our planet. There are sometimes news reports of a “close approach” ...

George Waltemath made an extraordinary claim: that the Earth had a second moon. It was supposed that it was much smaller and dimmer than the known moon. He predicted that on February 3rd of 1898 it would be visible in silhouette as it moved across the disk of the Sun, an event known as an astronomical transit.

Winslow Upton was skeptical of the existence of this long unnoticed moon, but nonetheless attempted to observe it.

We will be open tonight from 9-10:30 pm. There have been a lot of cloudy Tue. nights, so we decided to have a raindate this Thur.
