[/caption] The Earth’s mass is 5.9736 x 1024 kg. That’s a big number, so let’s write it out in full: 5,973,600,000,000,000,000,000,000 kg. You could also say the Earth’s mass is 5.9 sextillion tonnes. Phew, that’s a lot of mass. That sounds like a lot, and it is, but the Earth has a fraction of the …
The European Southern Observatory (ESO) is planning on building a massive – and I do mean massive – telescope in the next decade. The European Extremely Large Telescope (E-ELT) is a 42-meter telescope in its final planning stages. Weighing in at 5,000 tonnes, and made up of 984 individual mirrors, it will be able to …
[/caption] The basic chemistry for life has been detected the atmosphere of a second hot gas planet, HD 209458b. Data from the Hubble and Spitzer Space Telescopes provided spectral observations that revealed molecules of carbon dioxide, methane and water vapor in the planet’s atmosphere. The Jupiter-sized planet – which occupies a tight, 3.5-day orbit around …

[/caption]There are many interesting facts about comets. Some are about the different parts of the comet, others are about the effects that comets have had on humans and their behavior. This article will let you know about the different parts of the comet, the orbital habits of a comet, and the effects that comets have …
A dark red area discovered on dwarf planet Haumea appears to be richer in minerals and organic compounds than the surrounding icy surface. Since Haumea is so small and far away, it shows up in telescopes as just a point of light, but the spot was discovered by measuring changes in brightness as it rotates. …

[/caption] Scientists use crater distributions to tell the ages of planetary surfaces on rocky bodies. But how can the ages of gas planets be determined? Believe it or not, possibly from craters. Scientists from the National Institute of Astrophysics in Rome say that crater patterns on the two largest asteroids in the asteroid belt, Vesta …

The density of Venus is 5.204 grams per cubic centimeter. Need some kind of comparison? The density of Earth is 5.515 g/cm3. So Venus is definitely less dense than Earth. And it’s even less dense than Mercury. Of course, it’s much more dense than any of the outer planets, like Jupiter or Saturn. Scientists think …
[/caption] Mercury is the closest planet to the Sun, orbiting at only 57.9 million km. It’s classified as one of the “rocky” or terrestrial planets of the Solar System. But what is Mercury made of? How does Mercury’s composition compare to the other planets in the Solar System. Scientists believe that Mercury has an interior …
[/caption] Let’s compare and contrast the two most different planets in the Solar System, Mercury and Jupiter. Of course, you probably know that Mercury is the smallest planet in the Solar System while Jupiter is the largest planet in the Solar System. First, let’s just take a look at the physical measurements of Jupiter and …
[/caption] When you look up into the sky, if you are lucky, you see shining stars on a field of blue-black. Not all of these objects are stars though. Venus, which can be seen with the unaided eye from Earth, is the brightest planet in our Solar System. Venus was given the nickname evening star and …
