Today’s Astronomical Events – March 1st, 2015

The constellation Leo (the Lion) culminates at midnight on the 1st of the month. One of the few constellations to resemble the object or creature it’s meant to represent, it’s easily distinguished by the “backwards question-mark” asterism that forms the lions’ head. Regulus, its brightest star, lies almost on the ecliptic (the pale blue line in the images above) and, therefore, the Moon and planets pass very close by on a regular basis. For telescopic observers, the constellation is also home to a large number of galaxies.

Observers in the northern hemisphere have the help of the Big Dipper (aka the Plough, for those in the United Kingdom), part of the Ursa Major constellation, to help find Leo. Alternatively, look for the Moon and Jupiter and draw a line down as the pair are also pointing toward the constellation. A map of Leo can be found on the post for February 18th.
