Today I'm rather late with a new photo. It's mainly because I'm currently working on a photo book. I have sifted through so many pictures, edited them and moved them back and forth. In the meantime, I'm satisfied with it and can devote myself to Flickr again :D
Heute bin ich mit nem neuen Foto ziemlich spät dran. Es liegt vor allem daran, dass ich derzeit an einem Fotobuch sitze. Ich habe so viele Bilder gesichtet, nachbearbeitet und hin- und hergeschoben. Mittlerweile bin ich damit zufrieden und kann mich wieder Flickr widmen :D

"Dancers of Death": Iron sculptures by sculptor Wolf Spitzer
This composite image of data from three different telescopes shows an ongoing collision between two galaxies, NGC 6872 and IC 4970. X-ray data from NASA's Chandra X-ray Observatory is shown in purple, while Spitzer Space Telescope's infrared data is red and optical data from ESO's Very Large Telescope (VLT) is colored red, green and blue.
Astronomers think that supermassive black holes exist at the center of most galaxies. Not only do the galaxies and black holes seem to co-exist, they are apparently inextricably linked in their evolution. To better understand this symbiotic relationship, scientists have turned to rapidly growing black holes -- so-called active galactic nucleus (AGN) -- to study how they are affected by their galactic environments.
The latest data from Chandra and Spitzer show that IC 4970, the small galaxy at the top of the image, contains an AGN, but one that is heavily cocooned in gas and dust. This means in optical light telescopes, like the VLT, there is little to see. X-rays and infrared light, however, can penetrate this veil of material and reveal the light show that is generated as material heats up before falling onto the black hole (seen as a bright point-like source).
Despite this obscuring gas and dust around IC 4970, the Chandra data suggest that there is not enough hot gas in IC 4970 to fuel the growth of the AGN. Where, then, does the food supply for this black hole come from? The answer lies with its partner galaxy, NGC 6872. These two galaxies are in the process of undergoing a collision, and the gravitational attraction from IC 4970 has likely pulled over some of NGC 6872's deep reservoir of cold gas (seen prominently in the Spitzer data), providing a new fuel supply to power the giant black hole.

An age-defying star designated as IRAS 19312+1950 exhibits features characteristic of a very young star and a very old star. The object stands out as extremely bright inside a large, chemically rich cloud of material, as shown in this image from NASA’s Spitzer Space Telescope. A NASA-led team of scientists thinks the star – which is about 10 times as massive as our sun and emits about 20,000 times as much energy – is a newly forming protostar. That was a big surprise because the region had not been known as a stellar nursery before. But the presence of a nearby interstellar bubble, which indicates the presence of a recently formed massive star, also supports this idea.

This composite image of M31 (also known as the Andromeda galaxy) shows X-ray data from NASA's Chandra X-ray Observatory in gold, optical data from the Digitized Sky Survey in light blue and infrared data from the Spitzer Space Telescope in red. The Chandra data covers only the central region of M31 as shown in the inset box for the image.
New results show that the Chandra image would be about 40 times brighter than observed if Type Ia supernova in the bulge of this galaxy were triggered by material from a normal star falling onto a white dwarf star. This implies that the merger of two white dwarfs is the main trigger for Type Ia supernovas for the area observed by Chandra. Similar results for five elliptical galaxies were found. These findings represent a major advance in understanding the origin of Type Ia supernovas, explosions that are used as cosmic mile markers to measure the accelerated expansion of the universe and study dark energy. Most scientists agree that a Type Ia supernova occurs when a white dwarf star -- a collapsed remnant of an elderly star -- exceeds its weight limit, becomes unstable and explodes. However, there is uncertainty about what pushes the white dwarf over the edge, either accretion onto the white dwarf or a merger between two white dwarfs.
A Type Ia supernova caused by accreting material produces significant X-ray emission prior to the explosion. A supernova from a merger of two white dwarfs, on the other hand, would create significantly less. The scientists used the difference to decide between these two scenarios by examining the new Chandra data.
A third, less likely possibility is that the supernova explosion is triggered, in the accretion scenario, before the white dwarf reaches the expected mass limit. In this case, the detectable X-ray emission could be much lower than assumed for the accretion scenario. However, simulations of such explosions do not show agreement with the observed properties of Type Ia supernovas.

Not a bad looking woman at all. I can't believe what Gov. Spitzer was doing, lol! What the hell was he thinking? She is going to now get filthy rich without having to whore for it any more.
*Lol, that might not have come across as I meant it but you know what I mean.

The base of the tower was built in 1180 AD while the top was added in 1450 AD. It was part of the city wall.
What looks like a red butterfly in space is in reality a nursery for hundreds of baby stars, revealed in this infrared image from NASA's Spitzer Space Telescope. Officially named W40, the butterfly is a nebula – a giant cloud of gas and dust in space where new stars may form. The butterfly's "wings" are giant bubbles of hot, interstellar gas blowing from the hottest, most massive stars in this region.
The material that forms W40's wings was ejected from a dense cluster of stars that lies between the wings in the image. The hottest, most massive of these stars, W40 IRS 1a, lies near the center of the star cluster.
W40 is about 1,400 light-years from the Sun, about the same distance as the well-known Orion nebula, although the two are almost 180 degrees apart in the sky.

In the summer of 2022, NASA's James Webb Space Telescope released images from some of its earliest observations with the newly commissioned telescope. Almost instantaneously, these stunning images landed everywhere from the front pages of news outlets to larger-than-life displays in Times Square.
Webb, however, will not pursue its exploration of the universe on its own. It is designed to work in concert with NASA's many other telescopes as well as facilities both in space and on the ground. These new versions of Webb’s first images combine its infrared data with X-rays collected by NASA’s Chandra X-ray Observatory, underscoring how the power of any of these telescopes is only enhanced when joined with others.
The four galaxies within Stephan’s Quintet are undergoing an intricate dance choreographed by gravity. (The fifth galaxy, on the left, is an interloping galaxy at a different distance.) The Webb image (red, orange, yellow, green, blue) of this object features never-seen-before details of the results of these interactions, including sweeping tails of gas and bursts of star formation. The Chandra data (light blue) of this system has uncovered a shock wave that heats gas to tens of millions of degrees, as one of the galaxies passes through the others at speeds of around 2 million miles per hour. This new composite also includes infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue).

This Jan. 10, 2013, composite image of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory's Very Large Telescope with far-ultraviolet data from NASA's Galaxy Evolution Explorer (GALEX) and infrared data acquired by NASA's Spitzer Space Telescope. NGC 6872 is 522,000 light-years across, making it more than five times the size of the Milky Way galaxy. In 2013, astronomers from the United States, Chile, and Brazil found it to be the largest-known spiral galaxy, based on archival data from GALEX.

Gaseous swirls of hydrogen, sulfur, and hydrocarbons cradle a collection of infant stars in this composite image of the Orion Nebula, as seen by the Hubble Space Telescope and the Spitzer Space telescope. Together, the two telescopes expose carbon-rich molecules in the cosmic cloud of this star-formation factory located 1,500 light-years away.
Hubble's ultraviolet and visible-light view reveal hydrogen and sulfur gas that have been heated and ionized by intense ultraviolet radiation from the massive stars, collectively known as the "Trapezium." Meanwhile, Spitzer's infrared view exposes carbon-rich molecules in the cloud. Together, the telescopes expose the stars in Orion as a rainbow of dots sprinkled throughout the image.

Out of the dark and dusty cosmos comes an unusual valentine — a stellar nursery resembling a shimmering pink rosebud. This cluster of newborn stars, called a reflection nebula, was captured in 2004 by state-of-the-art infrared detectors onboard NASA's Spitzer Space Telescope.
A cluster of newborn stars herald their birth in this interstellar Valentine's Day commemorative picture obtained with NASA's Spitzer Space Telescope. These bright young stars are found in a rosebud-shaped (and rose-colored) nebulosity known as NGC 7129. The star cluster and its associated nebula are located at a distance of 3300 light-years in the constellation Cepheus.

Sixteen years ago, NASA launched its Spitzer Space Telescope into orbit around the Sun. Since the observatory launched on Aug. 25, 2003, it has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light. Spitzer's primary mission lasted five-and-a-half years and ended when it ran out of the liquid helium coolant necessary to operate two of its three instruments. But its passive-cooling design has allowed part of its third instrument to continue operating for more than 10 additional years. The mission is scheduled to end on Jan. 30, 2020.
This Spitzer image shows the giant star Zeta Ophiuchi and the bow shock, or shock wave, in front of it. Visible only in infrared light, the bow shock is created by winds that flow from the star, making ripples in the surrounding dust. Located roughly 370 light-years from Earth, Zeta Ophiuchi dwarfs our Sun: It is about six times hotter, eight times wider, 20 times more massive and about 80,000 times as bright. Even at its great distance, it would be one of the brightest stars in the sky were it not largely obscured by dust clouds.

A stellar Snowflake Cluster lurks within a cosmic Christmas tree!
2,600 light-years from Earth, the Christmas Tree Cluster is giving birth to new stars. Hidden to the naked eye behind thick dust, NASA's Spitzer Space Telescope can see the infant stars with infrared vision — the pink and red dots at the middle of this image, grouped in a pattern that resembles a snowflake.

In this large celestial mosaic taken by NASA's Spitzer Space Telescope and published in 2019, there's a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust. Some of these clusters are older than others and more evolved, making this a generational stellar portrait. This image is of the Cepheus C and Cepheus B regions and combines data from Spitzer's IRAC and MIPS instruments.
The grand green-and-orange delta filling most of the image is a faraway nebula, or a cloud of gas and dust in space. Though the cloud may appear to flow from the bright white spot at its tip, it is actually what remains of a much larger cloud that has been carved away by radiation from stars. The bright region is illuminated by massive stars, belonging to a cluster that extends above the white spot. The white color is the combination of four colors (blue, green, orange and red), each representing a different wavelength of infrared light, which is invisible to human eyes. Dust that has been heated by the stars' radiation creates the surrounding red glow.

The James Webb Space Telescope is aligned across all four of its science instruments, as seen in a previous engineering image showing the observatory’s full field of view. Now, we take a closer look at that same image, focusing on Webb’s coldest instrument: the Mid-Infrared Instrument, or MIRI.
The MIRI test image (at 7.7 microns) shows part of the Large Magellanic Cloud. This small satellite galaxy of the Milky Way provided a dense star field to test Webb’s performance.
Here, a close-up of the MIRI image is compared to a past image of the same target taken with NASA’s Spitzer Space Telescope’s Infrared Array Camera (at 8.0 microns). The retired Spitzer was the first observatory to provide high-resolution images of the near- and mid-infrared Universe. Webb, by virtue of its significantly larger primary mirror and improved detectors, will allow us to see the infrared sky with improved clarity, enabling even more discoveries.
For example, Webb’s MIRI image shows the interstellar gas in unprecedented detail. Here, you can see the emission from ‘polycyclic aromatic hydrocarbons’ – molecules of carbon and hydrogen that play an important role in the thermal balance and chemistry of interstellar gas. When Webb is ready to begin science observations, studies such as these with MIRI will help give astronomers new insights into the birth of stars and protoplanetary systems.
In the meantime, the Webb team has begun the process of setting up and testing Webb’s instruments to begin science observations this summer. Today at 17:00 CEST, Webb experts will preview these next two months of instrument preparations in a teleconference for media. Listen to the audio stream live at nasa.gov/live.
Webb is an international partnership between NASA, ESA and CSA. MIRI is part of Europe’s contribution to the Webb mission. It is a partnership between Europe and the USA; the main partners are ESA, a consortium of nationally funded European institutes, the Jet Propulsion Laboratory (JPL) and NASA's Goddard Space Flight Center (GSFC).

Newborn stars, hidden behind thick dust, are revealed in this image of a section of the so-called Christmas Tree Cluster from NASA's Spitzer Space Telescope. The newly revealed infant stars appear as pink and red specks toward the center and appear to have formed in regularly spaced intervals along linear structures in a configuration that resembles the spokes of a wheel or the pattern of a snowflake. Hence, astronomers have nicknamed this the "Snowflake Cluster."
Star-forming clouds like this one are dynamic and evolving structures. Since the stars trace the straight line pattern of spokes of a wheel, scientists believe that these are newborn stars, or "protostars." At a mere 100,000 years old, these infant structures have yet to "crawl" away from their location of birth. Over time, the natural drifting motions of each star will break this order, and the snowflake design will be no more.
While most of the visible-light stars that give the Christmas Tree Cluster its name and triangular shape do not shine brightly in Spitzer's infrared eyes, all of the stars forming from this dusty cloud are considered part of the cluster.
Like a dusty cosmic finger pointing up to the newborn clusters, Spitzer also illuminates the optically dark and dense Cone Nebula, the tip of which can be seen towards the bottom left corner of the image.
