Edited Hubble Space Telescope image of a cluster of galaxies around the largest one in the image, NGC 4874. Color/processing variant.
Original caption: In this NASA/ESA Hubble Space Telescope image, NGC 4874 is the brightest object, located to the right of the frame and seen as a bright star-like core surrounded by a hazy halo. A few of the other galaxies of the cluster are also visible, looking like flying saucers dancing around NGC 4874. But the really remarkable feature of this image is the point-like objects around NGC 4874, revealed on a closer look: almost all of them are clusters of stars that belong to the galaxy. Each of these globular star clusters contains many hundreds of thousands of stars. Recently, astronomers discovered that a few of these point-like objects are not star clusters but ultra-compact dwarf galaxies, also under the gravitational influence of NGC 4874. Being only about 200 light-years across and mostly made up of old stars, these galaxies resemble brighter and larger versions of globular clusters. They are thought to be the cores of small elliptical galaxies that, due to the violent interactions with other galaxies in the cluster, lost their gas and surrounding stars. This Hubble image also shows many more distant galaxies that do not belong to the cluster, seen as small smudges in the background. While the galaxies in the Coma Cluster are located about 350 million light-years away, these other objects are much further out. Their light took several hundred million to billions of years to reach us. Most unusually, the image also shows a very faint blue satellite trail, extending across the whole image, from the upper left corner of the frame to the lower right. Because Hubble’s cameras can only see a tiny part of the sky at one time, such trails are very rare. This picture was created from optical and near-infrared exposures taken with the Wide Field Channel of Hubble’s Advanced Camera for Surveys. The field of view is 3.3 arcminutes across.
Three opaque cherry red glass flower caps are accented simply with dark copper toned ball pins to form a bold cluter! Including the copper almond shaped earwires, handmade by MilenaS, these measure a little less than an inch, or about 2 1/2 cm.

Explosion prevention electric heater
1.small size and large power: the electric heater mainly uses cluster-type tubular electric heating elements.
2.fast thermal response, high thermal control accuracy, and high comprehensive thermal efficiency.
3.high heating temperature: the design working temperature may reach 850℃.
4.even media outlet temperature and high thermal control accuracy.
5.wide application scope and strong adaptability: the heater is applicable to explosion prevention or common applications, the explosion may reach Grade dII B and C, and the pressure resistance may reach 20MPa.
6.long service life and high reliability: the heater is made of special electric heating materials, the design surface power load is low, and multiple protection is adopted, so that the safety and service life of the electric heater will be significantly increased.
7.Available fully automated control: with the heater circuit design as required, the outlet temperature, flow, pressure and other parameters may be controlled automatically and conveniently and linked to computer.
8.Obvious energy conservation effect: the heat energy generated by power is almost fully transferred to the heating media. It is a form of energy utilization. Compared with common fuel heating, electric heating may generate high temperature (for example, the arc heating temperature may reach above 3000℃), thus being convenient to realize automatic control and remote control of temperature. The vehicle-mounted electric cup may enable certain temperature distribution of the heated object. The electric heating energy may generate heat inside the heated object directly, thus having high thermal efficiency and fast temperature increase, and realizing overall even heating or local heating (including surface heating) as well as vacuum heating and controlled atmosphere heating according to the requirements of heating technique.
In the process of electric heating, the generated amount of waste gas, residue and fume is small, thus keeping the heated object clean and not polluting the environment. Therefore, electric heating is widely used in the fields of production, research and experimentation, particularly in the manufacturing of mono-crystalline and transistors, machinery parts and surface hardening, ferroalloy smelting and artificial graphite production).
clustered bonnet ( mycena inclinata ) something is eating these fungi, and I think it is still there.
The Phoenix Cluster is an extraordinary galaxy cluster that is breaking several important astronomical records. The composite image on the left includes an X-ray image from Chandra (purple), an optical image from the 4-m Blanco telescope (red, green and blue), and an ultraviolet image from GALEX (blue). This galaxy cluster has been dubbed the "Phoenix Cluster" because of the constellation in which it is found, and because of its remarkable properties including an exceptionally high rate of star formation in its center. The artist's illustration on the right depicts the cluster's central galaxy surrounded by hotter (red) and cooler gas (blue). Flowing gas is shown in the ribbon-like structures, and the newly formed stars appear as smaller blue and white dots.
