Full Moon Rising over Mount Olympus
This is the full Moon rising over a ridge-line on Mount Olympus (Euboea), on Evia (Euboea) Island, Greece. This shot was taken from the village of Pissonas, just after sunset on May 29, 2018. Evia is the second largest Greek island in area and population, after Crete.
Though the Moon is the same angular size as it rises as it is when it's overhead, the full Moon looks huge when it's on or just above the horizon as a result of a well-known, but often debated optical illusion. This Moon illusion is related to the way we perceive the sky to be a finite distance from us and the way our brains judge distance. Take a look at the full Moon as it rises tomorrow night. It's the most distant full Moon of 2018. Nonetheless, it'll loom large when it breaks the horizon.

Le personnel qui travaille en permanence dans un laboratoire doit disposer des conditions de sécurité appropriées pour se protéger de toute tâche dangereuse. Une hotte de laboratoire est essentielle pour maintenir la qualité de l'air. C'est un type de système de ventilation qui assure la protection du personnel contre les émanations toxiques, les vapeurs et la poussière En outre, il agit comme une barrière physique pour protéger contre les déversements de produits chimiques, les réactions incontrôlées et les incendies.

Hi
Active Prominences on a Quiet Sun
Why is the Sun so quiet? As the Sun enters into a period of time known as a Solar Minimum, it is, as expected, showing fewer sunspots and active regions than usual. The quietness is somewhat unsettling, though, as so far this year, most days show no sunspots at all. In contrast, from 2011 - 2015, during Solar Maximum, the Sun displayed spots just about every day.
Maxima and minima occur on an 11-year cycle, with the last Solar Minimum being the most quiet in a century. Will this current Solar Minimum go even deeper? Even though the Sun's activity affects the Earth and its surroundings, no one knows for sure what the Sun will do next, and the physics behind the processes remain an active topic of research. The featured image was taken three weeks ago and shows that our Sun is busy even on a quiet day. Prominences of hot plasma, some larger than the Earth, dance continually and are most easily visible over the edge.

A colorful Crab Nebula (NGC 1952)
In this composite image made from data acquired by the Karl G. Jansky Very Large Array (VLA, radio data colored in red), NASA’s Spitzer Space Telescope (infrared, yellow), the NASA/ESA Hubble Space Telescope (optical wavelengths, green), ESA’s XMM-Newton telescope (ultraviolet radiation, blue) and NASA’s Chandra X-ray Observatory (X-ray, purple), you can see the Crab Nebula (Messier 1, NGC 1952) and the Crab Pulsar.
The young neutron star at its center is a remnant of the supernova SN 1054 (https://goo.gl/zPsvdM), which was observed on Earth in the year 1054. The nebula and pulsar are located in the constellation of Taurus (The Bull, https://goo.gl/9FLfn0), about 6,500 light-years away from Earth.
While only about 20 kilometers in diameter the Crab Pulsar is about 40 percent more massive than our Sun and its pulsar "beams" rotate once every 33 milliseconds, or 30 times each second. The strong radiation of the pulsar is driving the pulsar wind nebula (https://goo.gl/IATIk) surrounding it.
The Crab Nebula got its name from the Anglo-Irish astronomer William Parsons, 3rd Earl of Rosse (https://goo.gl/9U9KGN), who observed the object in 1840 and whose drawing of the nebula looked like a crab. (https://archive.org/stream/jstor-108366/108366#page/n5/mode/2up)

Take a look here for a video of the Crab Nebula in different wavelengths:
https://www.spacetelescope.org/videos/potw1720a/
It is a very fascinating and colorful image, showing the Crab Nebula over big parts of the electromagnetic spectrum. If you want to learn more about colors in astrophotography and why objects can look so different you should read this article I wrote for PhotographingSpace:

What is a pulsar (pulsating radio star)?
A pulsar is a type of neutron star, those are extremely dense and massive stars made up almost entirely of neutrons.They are the result of a gravitational collapse of a massive star following a supernova. Pulsars are highly magnetized and have short rotational periods. They are emitting beams of electromagnetic radiation which, when oriented in a way so a beam is facing Earth, can be detected. Because pulsars are rotating this beam rotates in an out of view resulting in a pulsating signal. More information here:

The personnel that continuously work in a laboratory need to have the proper safety conditions, in order to protect them from any hazardous tasks. A laboratory fume hood is vital to keep the quality of air in a laboratory. It is a type of ventilation system that provides personal protection against toxic fumes, vapours and dust. Also, it acts as a physical barrier to protect against chemical spills, runaway reactions and fires.
