Το «Φάντασμα του Δία», Ghost of Jupiter Nebula

Το Φάντασμα του Δία μέσα από τον φακό του Spitzer. This ghostly image from NASA's Spitzer Space Telescope shows the disembodied remains of a dying star, called a planetary nebula. Planetary nebulas are a late stage in a sun-like star's life, when its outer layers have sloughed off and are lit up by ultraviolet light from the central star. The Ghost of Jupiter, also known as NGC 3242, is located roughly 1,400 light-years away in the constellation Hydra. Spitzer's infrared view shows off the cooler outer halo of the dying star, colored here in red. Also evident are concentric rings around the object, the result of material being periodically tossed out in the star's final death throes. In this image, infrared light at wavelengths of 3.6 microns is rendered in blue, 4.5 microns in green, and 8.0 microns in red. Image Credit: NASA/JPL-Caltech/Harvard-Smithsonian CfA

Το διαστημικό τηλεσκόπιο Spitzer φωτογράφισε το «Φάντασμα του Δία». Πρόκειται για ένα πλανητικό νεφέλωμα που βρίσκεται σε απόσταση 1,400 ετών φωτός από τη Γη στον αστερισμό της Ύδρας. Η κωδική ονομασία του νεφελώματος είναι NGC 3242 και η μελέτη του ίσως αποκαλύψει νέα στοιχεία για τα πλανητικά νεφελώματα.

It's a weed, it's Jupiter, no it's - actually planetary nebula NGC 3242. After a star like our Sun completes fusion in its core, it throws off its outer layers it a striking display called a planetary nebula. NGC 3242 is such a planetary nebula, with the stellar remnant white dwarf star visible at the center. This nebula is sometimes called "The Ghost of Jupiter" for its similar appearance to the familiar planet. NGC 3242 is much farther away however, than the measly 40 light-minutes distance to Jupiter. In fact, by comparing the apparent expansion rate with the actual rate determined from Doppler studies, astronomers have estimated the distance to NGC 3242 to be about 1400 light-years away. The red FLIERs visible near the edges of the nebula remain mysterious. Credit: B. Balick (U. Washington) et al., WFPC2, HST, NASA

Ένα πλανητικό νεφέλωμα αποτελείται από ένα επεκτεινόμενο κέλυφος ιονισμένου αερίου που αποβάλλεται από άστρα τα οποία βρίσκονται στα τελευταία στάδια της ζωής τους. 

This trio of ghostly images from NASA’s Spitzer Space Telescope shows the disembodied remains of dying stars called planetary nebulas. In the spirit of Halloween, scientists are releasing a trio of stellar ghosts caught in infrared light by NASA’s Spitzer Space Telescope. All three spooky structures, called planetary nebulas, are in fact material ejected from dying stars. As death beckoned, the stars’ wispy bits and pieces were blown into outer space.

Οι ειδικοί εκτιμούν ότι τα πλανητικά νεφελώματα μπορεί να παίζουν σημαντικό ρόλο στη χημική εξέλιξη ενός γαλαξία.

Η «μάγισσα» που γεννά άστρα, 'Witch Head' Brews Baby Stars

Το «Κεφάλι της Μάγισσας» όπως το κατέγραψε το τηλεσκόπιο WISE. A witch appears to be screaming out into space in this new image from NASA's Wide-Field Infrared Survey Explorer, or WISE. The infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE's detectors. The Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee. WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE. The reactivation came after the spacecraft was put into hibernation in 2011, when it completed two full scans of the sky, as planned. Image credit: NASA/JPL-Caltech

Το διαστημικό τηλεσκόπιο WISE κατέγραψε νέες λεπτομερείς εικόνες ενός εντυπωσιακού νεφελώματος που βρίσκεται σε απόσταση 900 ετών φωτός από εμάς στον αστερισμό του Ηριδανού. Η κωδική του ονομασία είναι IC 2118 αλλά οι επιστήμονες το έχουν βαφτίσει «Το Κεφάλι της Μάγισσας» επειδή όταν ανακαλύφθηκε σε κάποιους θύμισε το προφίλ μιας μάγισσας. 

Blue-white Rigel via Clark Planetarium.

Το νεφέλωμα βρίσκεται κοντά στο γιγάντιο άστρο Rigel το φως του οποίου λούζει το νεφέλωμα. Το φως του Rigel σε συνδυασμό με το φως των άστρων που γεννιούνται μέσα στο νεφέλωμα το κάνουν να λάμπει στο υπέρυθρο του φάσματος το οποίο παρατηρεί το WISE.
