Mars Forms Triangle With Moon and Star Tonight
As the evening twilight deepens around 8:30 p.m. local time Tuesday night (April 3), check out the southeast sky. Weather permitting, a waxing gibbous moon will be shining bright, but it won’t be alone.
Situated well above the moon will be two bright “stars.” I’ve placed the word stars in quote marks, because one of those stars is in reality a planet: the so-called Red Planet, Mars.
The planet will form a cosmic triangle with the moon, Mars and bright star Regulus. The arrangement can be seen in the sky map of Mars accompanying this planet viewing guide.

    10 Moons Every Person Should Know

    Pretty much everyone can rattle off the names of our solar system’s eight (formerly nine) planets, but ask the average person to list some moons and you’ll be lucky if they can tell you more than two or three.

    Now, you obviously can’t expect people to remember the name of every single satellite in the solar system (after all, they outnumber the planets by around 20 to 1), but if you have even the slightest interest in astronomy, it wouldn’t kill you to be familiar with at least an even ten. So with that in mind, we’ve assembled this reference guide to ten of the solar system’s most noteworthy moons.

    1. Moon: Europa
    Parent Planet: Jupiter
    Why You Should Know it: Despite being covered by distinctive, criss-crossing cracks and ridges, Europa’s water-ice surface is largely free of craters, making it perhaps the smoothest solid body in the entire solar system. More interesting than Europa’s frozen exterior, however, is what lies hidden beneath it.

    2. Moon: Io
    Parent Planet: Jupiter
    Why You Should Know it: Io is very close in size to our own moon, but it couldn’t be more different. Despite having a mean surface temperature of less than -250 degrees Fahrenheit, Io is home to over 400 raging volcanos, making it the single most geologically active object in the solar system.

    3. Moon: Mimas
    Parent Planet: Saturn
    Why you should know it: This list is an important reference for any self-respecting science geek, but Mimas is especially relevant for fans of science fiction for what should be obvious reasons. In brief: Mimas is no space station. It’s a moon. Like many of Saturn’s orbiting bodies, Mimas is small and icy, but it’s also home to “Herschel” — the name astronomers have given the massive crater situated on the moon’s leading hemisphere.

    4. Moon: Enceladus
    Parent Planet: Saturn
    Why You Should Know it: Enceladus is one wacky little moon. Like Europa, its surface is covered in water ice, but it’s also home to some of the most impressive geysers in the solar system. Scientists had suspected for years that Enceladus was venting water vapor from its surface, but it wasn’t until 2005 that they had direct visual confirmation that the moon was doing so by spewing jets of the stuff from geysers on its surface.

    5. Moon: Triton
    Parent Planet: Neptune
    Why You Should Know it: Of all the biggest, “major” moons in the solar system, Triton is the only one that orbits in a direction opposite that of its parent planet’s rotation. Astrophysicists call this a “retrograde orbit,” and it’s typical of moons that have been “captured” by their parent planet.

    6. Moon: Iapetus
    Parent Planet: Saturn
    Why You Should Know it: Iapetus may be one of the most mysterious moons we’ve ever discovered. For one thing, it is two completely different colors; the moon’s trailing hemisphere is as bright and reflective as snow, but its leading hemisphere is as dark as freshly poured asphalt — a characteristic that has led many astronomers to refer to it as the “painted” or “yin-yang” moon.

    7. Moon: Phobos
    Parent Planet: Mars
    Why You Should Know it: Mars’ moon Phobos may not be the biggest moon on this list. It may not have the most interesting geology, or the most peculiar orbit, or the most promising environment when it comes to harboring extraterrestrial life. Be that as it may, there is a very, very good chance that it will become the second moon — and the third cosmic body — to host human travelers on mankind’s journey out into the Universe.

    8. Moon: Titan
    Parent Planet: Saturn
    Why You Should Know it: If moons could be considered for reclassification under planetary status, Titan would be the first to come under review. It is the only moon in the entire solar system with a dense atmosphere (which can be clearly seen in the form of an enveloping haze in many recent Cassini images, including the one featured here); it experiences rain and snow; and it’s even home to geological features like lakes, valleys, plains and deserts. In fact, according to NASA’s Dr. Rosaly Lopes, “Titan looks more like the Earth than any other body in the Solar System.”

    9. Moon: Hyperion
    Parent Planet: Saturn
    Why You Should Know it: Phil Plait — astronomer extraordinair and master of ceremonies over at Bad Astronomy — once called Hyperion “the solar system’s weirdest moon” — and that’s saying something. For one thing, Saturn is home to some pretty wonky moons (just look at how many of the natural satellites on this list orbit the ringed planet); secondly, Phil Plait has written about some weird moons in his day — so what makes Hyperion the weirdest? Well, a lot of things, but for starters: the loofah-like moon happens to be weirdly foamy.

    10. Moon: Moon
    Parent Planet: Earth
    Why You Should Know it: It’s hard to go wrong with the original. Sure, it’s the first moon humans ever observed, but it wasn’t until the 1950s that we finally managed to get a glimpse of its far side; and just last week we learned that the Moon may have been partly responsible for sinking the Titanic, demonstrating that our Moon has been — and will always be — a source of wonder and mystery.

Most Detailed View of a Solar Eclipse Corona

Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun’s outer atmosphere, is an alluring sight.

But the subtle details and extreme ranges in the corona’s brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured above, however, using multiple images and digital processing, is a detailed image of the Sun’s corona taken during the 2008 August total solar eclipse from Mongolia.
