Six nature facts related to coronaviruses

Did you know that around 60 per cent of all infectious diseases in humans are zoonotic, as are 75 per cent of all emerging infectious diseases, in other words they come to us via animals?

Zoonoses that emerged or re-emerged recently are Ebola, bird flu, Middle East respiratory syndrome (MERS), the Nipah virus, Rift Valley fever, sudden acute respiratory syndrome (SARS), West Nile virus, Zika virus disease, and, now, the coronavirus. They are all linked to human activity.

The Ebola outbreak in West Africa was the result of forest losses leading to closer contacts between wildlife and human settlements; the emergence of avian influenza was linked to intensive poultry farming; and the Nipah virus was linked to the intensification of pig farming and fruit production in Malaysia.

Scientists and specialists working at the United Nations Environment Programme (UNEP) have been pulling together the latest scientific facts about the coronavirus—what we know about the virus and what we don’t know.

While the origin of the outbreak and its transmission pathway are yet to be discovered, here are six important points worth knowing:

1. The interaction of humans or livestock with wildlife exposes them to the risk of spillover of potential pathogens. For many zoonoses, livestock serve as an epidemiological bridge between wildlife and human infections.

2. The drivers of zoonotic disease emergence are changes in the environment—usually the result of human activities, ranging from land use change to changing climate; changes in animals or human hosts; and changes in pathogens, which always evolve to exploit new hosts.

3. For example, bat-associated viruses emerged due to the loss of bat habitat from deforestation and agricultural expansion. Bats play important roles in ecosystems by being night pollinators and eating insects.

4. Ecosystem integrity underlines human health and development. Human-induced environmental changes modify wildlife population structure and reduce biodiversity, resulting in new environmental conditions that favour particular hosts, vectors, and/or pathogens.

5. Ecosystem integrity can help regulate diseases by supporting a diversity of species so that it is more difficult for one pathogen to spill over, amplify or dominate.

6. It is impossible to predict where the next outbreak will come from or when it will be. Growing evidence suggests that outbreaks or epidemic diseases may become more frequent as climate continues to change.

“Never before have so many opportunities existed for pathogens to pass from wild and domestic animals to people, says UNEP Executive Director Inger Andersen. “Our continued erosion of wild spaces has brought us uncomfortably close to animals and plants that harbour diseases that can jump to humans.”

UNEP staff are continuing work in these important areas. Notes shared by its Science Division are available online with additional information, including a list of questions yet to be answered.

Nature is in crisis, threatened by biodiversity and habitat loss, global heating and toxic pollution. Failure to act is failing humanity. Addressing the novel coronavirus (COVID-19) pandemic and protecting ourselves against future global threats requires sound management of hazardous medical and chemical waste; strong and global stewardship of nature and biodiversity; and a clear commitment to “building back better”, creating green jobs and facilitating the transition to carbon neutral economies. Humanity depends on action now for a resilient and sustainable future.

This is known as the bootes void it's basically a large chunk of emptiness in the universe it's a massive void that reaches over 200 million light years in diameter and covers 0.27% of the observable universe. It's known to be one of the largest things in the entire universe! What's mysterious is that nobody knows why nothing is there, what're your thoughts?

Planetary Imaging through Manual Dobsonian using Stacking method.

Why stack?

Stacking involves digital integration of pixel data in order to increase Signal to Noise (S/N) ratio for getting better quality output than the single shot images.

Notice the improvement in final output using Stacking method as compared to single frame from input video.

Simple steps for getting better output quality in stacking.

1] Use high speed camera capable of capturing video frames at higher FPS at least 60 FPS or more this helps to gather more frames in less duration & thereby helps to avoid planet's rotation speed causing smear in output if done using longer duration videos captured at lower FPS.

2] Capture at least 3-4 videos of 15-30 sec duration each by keeping planet disc consistent in center of the frame. This will help to get more frames for stacking even for slower FPS cameras.

3] Use Planetary Imaging PreProcessor (PIPP) for making stabilized output AVI files & use that as input with Stacking program. This is particularly useful for those don't have tracking mount & have shaky videos where planet disc keeps bouncing all over the frame.

4] Use Autostakkert2 program for stacking it can handle large AVI video files & produce better quality output thank Registax

5] Allow telescope to cool down to surrounding temperature after you bring it outside from the storage place. This allows to steady the thermal currents inside OTA (tube) & produce less turbulent images & thus helps to capture fine details.

6] Check for Tutorials on YouTube describing image stacking & practice often.

*Most importantly stacking process produce better quality results regardless of equipment used. So don't worry if you have smaller aperture telescope or lower FPS camera (simple we**am or digicam) just keep going by Tutorial videos & practice as much possible to improve skills & thus get better results each time.

Equipment -
ZWO ASI120MC-S camera on Orion 3X Barlow with Sky-watcher 10 inch Dobsonian.

All images captured on 10 Mar 2016 from Dombivli, India.

Do you know??

You become taller in Space.

Another change to the human body in micro-gravity is that spine straightens out, as gravity is not pushing you down. In fact you can be up to as much as 5cm taller in the Space Station.

This series of images from NASA's Hubble Space Telescope shows how the ring system around the distant planet Uranus appears at ever more oblique (shallower) tilts as viewed from Earth - culminating in the rings being seen edge-on in three observing opportunities in 2007. The best of these events appears in the far right image taken with Hubble's Wide Field Planetary Camera 2 on August 14, 2007.
The edge-on rings appear as two spikes above and below the planet. The rings cannot be seen running fully across the face of the planet because the bright glare of the planet has been blocked out in the Hubble photo (a small amount of residual glare appears as a fan- shaped image artifact). A much shorter color exposure of the planet has been photo- composited to show its size and position relative to the ring plane.
Earthbound astronomers only see the rings' edge every 42 years as the planet follows a leisurely 84-year orbit about the Sun. However, the last time the rings were tilted edge-on to Earth astronomers didn't even know they existed.
With further analysis of the Hubble data, astronomer Mark Showalter of the SETI Institute in Mountain View, Calif., hopes to detect some of the small moons that may shepherd the debris into distinct rings.
Until Voyager 2 flew by Uranus in January 1986, the rings were only known from the way they temporarily blocked the light of stars passing behind the planet. Hubble provided some of the first images of the ring system as viewed from Earth's distance of approximately 2 billion miles. The advent of adaptive optics gave ground-based observers using large telescopes comparatively sharp views.
The rings were discovered in 1977, so this is the first time for a Uranus ring crossing to be observed from Earth. Earth's orbit around the Sun permits three opportunities to view the rings edge-on: Uranus made its first ring crossing as seen from Earth on May 3; it made its second crossing on August 16; and will cross for the third time on February 20, 2008. Though the last ring crossing relative to Earth will be hidden behind the Sun, most of Earth's premier telescopes, including Keck, Hubble, the European Southern Observatory's Very Large Telescope and the Hale Telescope on Mt. Palomar, plan to focus on the planet again in the days following December 7, 2007. On December 7 the rings will be perfectly edge-on to the Sun.
Showalter is a member of a team led by Imke de Pater of the University of California, Berkeley, who reported that the rings of micron-sized dust have changed significantly since the Voyager 2 spacecraft photographed the Uranus system 21 years ago. Observations were also gleaned from near-infrared adaptive optics observations with the Keck II telescope on May 28, 2007, and reported in an article appearing on August 23 in Science Express, the online edition of Science Magazine.
