Eccentricity

2025/04/13

Two planets are at aphelion this week. Their aphelion and perihelion distances reveal just how elliptical their orbits are.

Sideral and solar days

SkyCaramba ·

2025/04/06

Two planets are moving eastward in the morning sky. But for now, the sun's moving eastward faster. The way things look, the stars are climbing the sky each morning faster than those planets or the sun. I'll explain this effect of the difference between the sidereal and solar days.

Color changing stars

SkyCaramba ·

2025/03/30

One more time, the moon reaches as far north as it can.Try to see Venus in the morning.Mars rides high at dusk.And sometimes, stars seem to change colors because of other stars next to them. You can try to make it happen in your own telescope!

Partial solar eclipse and counting lunar months

SkyCaramba ·

2025/03/23

Venus and Mercury are on the other side of the sun. A partial solar eclipse happens in the northern hemisphere. And some people keep count of how many lunar months have gone by since some moment.

Moon farthest south and equinox egg absurdity

SkyCaramba ·

2025/03/16

The moon's heading toward the farthest south it will go for the next two decades. Venus and Mercury head to conjunction. And why is there an old tale about being able to stand an egg on its end only on the equinox?

00:05:41

Total lunar eclipse and astronomy times

SkyCaramba ·

2025/03/09

Planets are disappearing from the evening sky, but Venus is a good guide for finding Mercury. There's a total lunar eclipse this week. You can usually still see some lunar features during totality. And Universal Time isn't universally understood.

00:05:29

Why we can see nebulae

SkyCaramba ·

2025/03/02

Saturn's lost in the sun glow as it leaves the evening sky. Mercury and Venus are leaving soon. Last chance to see the moon as far north as it goes. Find out about next week's total lunar eclipse. And learn why we see nebulae.

Ringless Saturn--out of sight

SkyCaramba ·

2025/02/23

Sometimes, Saturn appears ringless. We're about to cross the ring plane, from which we see--or don't see--the rings edge-on. Unfortunately, we won't get to see this phenomenon when it happens in a few weeks.

00:05:34

Orbital undulations affecting the lunar looking

SkyCaramba ·

2025/02/16

The same side of the moon is always facing us, so it seems like we should see just half of it. But we actually see more, thanks to the tidal lock not being super tight.Some evening planets are sinking into the sunset, while others still ride high at dusk.

00:05:08

Change of direction

SkyCaramba ·

2025/02/09

Why do the planets seem to go back and forth in our sky when they're all going the same way around the sun?Mercury's about to emerge into the evening sky. No pre-dawn planet watching for now. So get to know the current morning stars. Is Cygnus flying in the right place?

00:05:49

Air in the way

SkyCaramba ·

2025/02/02

Even though we see through air, it's not as transparent as we think. It gets in the way. Venus, Saturn, and Neptune are close on the celestial dome. They're fairly easy to see for now. Mars moves deeper into Gemini. Jupiter resumes direct motion this week.

00:04:49

The dog nights of winter

SkyCaramba ·

2025/01/26

Mars pushes into Gemini. Jupiter prepares to turn around. Venus enters Pisces. And with two dogs crossing the sky, why don't northern hemisphere residents call these the dog nights of winter?

00:05:10

Pondering predictions for the Blaze Star

SkyCaramba ·

2025/01/19

Venus soars above Saturn. Jupiter and the Hyades are high at dusk. Mars passes Pollux. And how can scientists know when the Blaze Star in Corona Borealis will flare up?

00:05:23

How the celestial twins are half-brothers

SkyCaramba ·

2025/01/12

The moon passes in front of Mars. Venus passes Saturn. The moon's near Pollux and Mars. And let's discuss how Gemini, the celestial twins, aren't full brothers.

00:05:31

Perihelion has passed

SkyCaramba ·

2025/01/05

Jupiter remains near the Hyades. The moon visits Venus and Saturn. Mercury continues on its way out of the morning sky. And Earth is getting farther away from the sun. But if you think that's why it's cold where you are now, you're wrong.

00:05:16

Quick! See some quadrantids

SkyCaramba ·

2024/12/29

Venus is approaching greatest elongation and heading toward Saturn. Jupiter and Mars are good sights all night. Mercury's still a morning object. And this week is a good time to look for Quadrantid meteor showers.

00:04:25

Plenty of planet watching all night

SkyCaramba ·

2024/12/22

Venus passes through Capricornus on the way toward Saturn in Aquarius. Jupiter heads toward the Hyades. Mars goes back toward Gemini. Mercury moves by the scorpion's head.

Longest solar days of the year

SkyCaramba ·

2024/12/15

Lunistice and solstice in the same week. Venus approaches Saturn. The moon visits Jupiter and Mars. Mercury hovers near Antares. And these days, high noon to high noon takes the longest.

Genesis of the Geminids

SkyCaramba ·

2024/12/08

The moon occults Saturn. Mercury moves to the morning. Vesper Venus. Mars turns around. And it's Geminid meteor time. Some scientists think those meteors didn't come from a defunct comet's dust after all.

00:04:49

Mars pauses at the beehive

SkyCaramba ·

2024/12/01

A new month and a new moon. Mercury at inferior conjunction. Jupiter at opposition. The moon passes by or in front of Saturn. and Mars turns around at the Beehive Cluster.
