Venus moves into the morning.

Jupiter and Uranus rise in late evening.

Saturn's almost at opposition.

Mercury and Mars barely grace the evening sky.

And the moon passes in front of the reddish star Antares in an event reminiscent of the moon-Mars occultation in December.

Leo dives into the sunset. Mercury and Mars finish their pairing nearby. Saturn continues approaching opposition. Jupiter rises earlier. And Venus transitions to morning.

The moon will soon occult Antares.

Two galaxies--one of them the one we live in--will merge in a few billion years. What will we call the new amalgamation? Will people even be around to call it anything?

A lonely star in the southern sky is orbited by rings of dust.

Different planets axes point at different north and south celestial poles. Find out where the north and south stars are on bodies other than Earth.

Venus heads toward inferior conjunction.

The Perseid meteor shower will peak soon.

Two meteor showers peak early this week. Evening planet watching's getting hard. Saturn's approaching opposition. And what's with that face on Mars?

Mars, Venus, and Mercury are evening objects near Regulus this week.

Saturn's close to Sigma Aquarii.

Pluto's up all night. It's hard to see. Its five moons are even harder to see. Mathematics helped prove--at least to some people--that the first known Plutonian moon exists. It certainly wasn't distinct in the first pictures.

Lots of things to talk about this week:

Mercury becomes an evening object.

Mars is close to Regulus.

Venus turns around.

Spectroscopic binaries.

The moon passes Saturn and Jupiter.

Solstice on Mars.

The summer triangle.

Star-crossed lovers.

The first of four so-called supermoons is this week.

What looks like one star in the scorpion is actually six!

Venus pursues Mars in the evening sky.

Mercury's at perihelion and heading toward conjunction with the sun.

The June solstice is this week. A Greek mathematician observed shadows during the solstice, had people make measurements, ran some calculations, and came up with the first known estimate of how big around the earth is.
