SUNSET: 
Meet Capella, the Goat Star
Capella is the sixth-brightest star in the sky — and it's more than one star! The main two stars in the system are near-twins, bright yellow giants.
Meet Arcturus: Guardian of the Bear
Arcturus is one of the brightest stars in the sky — a cool red giant in Bootes, the Herdsman, that's often tied mythologically to Ursa Major, the Bear.
Meet Antares: The Star That Is Not Mars
Antares is a red supergiant that — like Betelgeuse — will one day go supernova.
See the Phases of Venus
If you have a set of binoculars or a telescope, watch for Venus’s thinning crescent over the next couple weeks.

Meet Dubhe, Giant of the Big Dipper
Of the seven stars in the Big Dipper, Dubhe is an outlier. Its color, speed across the sky, and evolutionary age set it apart from its comrades.
Meet the Pleiades, the Seven Sisters
The Pleiades are actually a star cluster of thousands of stars enshrouded in dust and gas, and they're easy to find if you know where to look.
What are Asteroids, Comets & Meteors?
Asteroids, comets, meteors — what’s the difference? Is a comet just an asteroid with a tail? And what makes a meteor different from the other two?
Meet Altair, the Eagle’s Eye
Altair, centerpiece of Aqulia, the Eagle, is the twelfth-brightest star in the night sky and one of the closest stars to Earth.
Meet Barnard’s Star, Our Red Dwarf Neighbor
This faint red dwarf star is famous not because it's bright but because it's fast-moving — you can actually see it moving across the sky if you track it over several years.
Meet Canopus, the Second Brightest Star
The second-brightest star after Sirius, Canopus is visible in southern skies, shining out of the constellation Carina.
Meet Spica, the Ear of Grain
Meet Spica, the "ear of grain" in the constellation Virgo. This bright star is actually part of a binary orbiting so closely, they tug each other out of spherical shapes and whirl around each other every four days.
Meet Vega, the Jewel of the Lyre
Meet Vega, the fifth-brightest star in the night sky and the most brilliant star in the constellation Lyra. Vega is in the prime of its life on the main sequence, but it's notable for its speedy spin and infrared-radiating debris disk.
How to “See” Interstellar Space Probes
So far, humans have sent five probes into space that are or will go far beyond the solar system: the Pioneers, the Voyagers, and New Horizons. As an exercise in fun, here's how you can find those probes' locations on the sky.
Meet Fomalhaut, the Autumn Star
The bright star Fomalhaut, home to three suns plus a planet, peeks over the southern horizon in early autumn evenings in the Northern Hemisphere.
Meet Rigel, Orion's Blue Suede Shoe
The seventh brightest star in the sky, blue-white Rigel shines brilliantly at the left foot of Orion and is actually a trio: a supergiant orbited by a pair of Sun-like stars.
Meet Deneb, the Bright but Distant Star
Deneb, in the constellation Cygnus, is a star that shines brilliantly despite being one of the farthest you can see with the unaided eye.
Meet Pollux, the Red Giant with a Planet
Meet the stars: Pollux, one of the Twins in the sky, is a star that has swelled into its red giant phase while holding onto its Jupiter-like exoplanet, dubbed Thestias.
Meet Regulus, Little King of the Ecliptic
Meet Regulus A, dubbed "Little King" and "Heart of the Lion," among the 25 brightest stars in the sky. The star belongs to a complex system, including a close white dwarf companion that makes its ultimate fate uncertain.
Meet Betelgeuse, the Red Giant of Orion
Betelgeuse, the brilliant red star at the right shoulder of Orion, is a supergiant whose girth extends out to the orbit of Jupiter.
