A star’s luminosity is its true brightness. Nearly every star you see with the unaided eye is more luminous than our sun.

Watch for the waxing moon. On the evening of February 26, 2015 – and for a few nights afterwards – it arcs north of the constellation Orion and south of the ecliptic.
From far-northern latitudes, the moon will cover Aldebaran for up to an hour. The rest of us get an awesome view of this bright star right next to the moon.
Tonight’s moon shines near the star Aldebaran and the dipper-shaped Pleiades star cluster. The very bright object in the east is the planet Jupiter.
You might notice it a smudge in a dark sky, with three times the moon’s diameter. It’s really a wondrous cluster of stars called the Beehive, or M44.
In late February 2015, the Southern Hemisphere has a ringside seat to this morning apparition of Mercury. Tips on finding Mercury from the Northern Hemisphere, too.
This is the closest conjunction of Venus and Mars since 2008. They won’t couple up this closely again until 2017. Look west after sunset!
Venus and Mars in the west after sunset – and the waxing moon. It doesn’t get any better. Plus … can one planet ever pass in front of another and blot it from view?
Planets and moon – west after sunset – are about to be spectacular. Friday and Saturday nights awesome. And tonight? Could be wonderful, especially if you catch the very young moon.
It’s a new moon at its closest to Earth. Expect higher-than-usual tides in the days ahead. It’s also the third of four new moons in this present season.
