Orion and the Horse-head in Infrared

This wide image of the Orion Molecular Cloud Complex features the Flame nebula (NGC 2024) and the Horsehead nebula (NGC 2023). In this infrared image, the Horsehead can be seen on the bottom right as a small wisp of gas protruding from the complex. The colors in this image do not represent visible light because it was imaged with the Spritzer Space Telescope - which can only see infrared light. As a result, scientist must map temperatures to colors. Cooler objects, such as the dust of the nebulae, appear green and red and hotter objects appear more blue. Astronomers are essentially “shifting” the infrared light into the visible spectrum.

Solar System: Things to Know This Week

Here are a few things you should know about our solar system this week:

1. Gearing Up for a Grand Finale

There’s just a year left until the Cassini mission begins its Grand Finale – the final phase of its mission, during which the spacecraft will dive repeatedly between the planet and the rings. To get ready, the Cassini team has launched an enhanced, mobile device-friendly version of the mission website. The site includes information about Cassini, Saturn, the moons and the rings – but it also tells the human stories behind one of the most ambitions expeditions of all time.

2.Caught in Transit

On Monday, May 9, the planet Mercury will cross directly in front of the sun, an event that hasn’t occurred since 2006 and won’t happen again until 2019. Find out how to watch HERE.  

3. A Moon for Makemake

Our Hubble Space Telescope has spotted a small, dark moon orbiting Makemake (pronounced “MAH-kay MAH-kay). Make make is the second brightest icy dwarf planet – after Pluto – in the faraway Kuiper Belt.

4. The Age of the Aquarids

The Eta Aquarid meteor shower is the first of two showers that occur each year as a result of Earth passing through dust released by Halley’s Comet. This year, it should peak on the night of May 5/6. Get tips for watching HERE.

5. The Southern Lights of Saturn

On May 4, Cassini will reach periapse, the closest point to Saturn in the spacecraft’s orbit. At about this time, Cassini’s cameras will monitor Saturn’s south polar aurorae, and also image the bright limb of the planet to better understand its upper haze layers.

The Trapezium is that a space ghost?

Einstein presented his theory of relativity in 1916, but for an entire century nobody could find physical proof of black holes. In 2016, scientists finally detected gravitational waves that emitted from 2 black holes colliding, proving that such things not only exist, but that Einstein was right all along. Source

How Well Do you Know Neptune?

Dark, cold and whipped by supersonic winds, Neptune is the last of the hydrogen and helium gas giants in our solar system. More than 30 times as far from the sun as Earth, the planet takes almost 165 Earth years to orbit our sun! In fact, in 2011, Neptune completed its first orbit since its discovery in 1846.

Here are a few things you might not know about the windiest planet:

If the sun were as tell as a typical front door, the Earth would be the size of a nickel and Neptune would be about as big as a baseball.

Neptune orbits our sun, a star. Neptune is the eighth planet from the sun at a distance of about 4.5 billion km (2.8 billion miles) or 30.07 AU. 

One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once)

Neptune makes a complete orbit around the sun (a year in Neptunian time) in about 165 Earth years (60,190 Earth days)

Neptune has six rings

Voyager 2 is the only spacecraft to have visited Neptune

Neptune has 13 moons. They are named after various sea gods and nymphs in Greek mythology

Did you know that Neptune has storms?

Similar to Jupiter, Neptune has storms that create gigantic spots in its atmosphere…well, it did. When Voyager 2 flew past Neptune in 1989, it tracked and imaged the “Great Dark Spot” — a storm larger than the entire Earth! When the Hubble Space Telescope imaged Neptune the spot had disappeared, only to be replaced with two smaller storms, which in turn also disappeared.

Interstellar 2014

“We used to look up at the sky and wonder at our place in the stars. Now we just look down, and worry about our place in the dirt.”

Psychedelic Pluto : New Horizons scientists made this false color image of Pluto using a technique called principal component analysis to highlight the many subtle color differences between Plutos distinct regions.
