NASA bids farewell to MESSENGER, its Mercury orbiter

Science Focus

original post »

A bit over 3,900 days ago, NASA sent a probe on a meandering course through the inner Solar System. After seven years of gravitational maneuvering, MESSENGER finally arrived at its destination: Mercury, which it became the first spacecraft to visit since 1975's Mariner 10 flyby. Since then, it's been gathering data without much fuss, and without the attention-grabbing surroundings that Cassini benefits from while orbiting Saturn. But its time there has come to an end; out of fuel, the probe is expected to crash into the planet's surface tomorrow.

Mercury's lack of glamor hasn't meant for lack of interesting science. MESSENGER stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging, which gives you some sense of the extensive suite of instruments it carries.

We've covered a number of its findings. Despite its proximity to the Sun, MESSENGER found hints of water and other volatile chemicals in the shadows of crater rims at the planet's poles. Researchers had also suggested the planet had shrunk as it cooled off after its formation, but MESSENGER was able to put some numbers on the shrinkage: its radius went down by somewhere between five and seven kilometers.

Stellar Nursery R136 in the Tarantula Nebula Rectangular Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: galaxies, dorneblmc, stellar nursery, 30 doradus nebula, large magellanic cloud, amazing hubble images, tarantula nebula, r136, star cluster, astronomy pictures, massive stars

Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.
