Transit of Mercury: Make sure to use special filters for eyes

If you are going to watch this transit on Monday, 9th May, make sure that you have special approved filters. Without protection, looking straight at the Sun can cause permanent damage to your eyesight. The Royal Astronomical Society states that direct sunlight can permanently damage the retina. This could lead to blindness or loss of vision. Mercury, the smallest and closest planet in the Solar System, passes between the Sun’s Sun and Earth. This is the Mercury’s path during its transit 10 years ago (2006). Mercury is not large enough to have any effect on the amount of sunlight hitting the Earth’s surface. Image: Mercury doesn’t block the Sun. However, this isn’t like a lunar Eclipse when the Moon completely blocks the Sun and all things go dark. Mercury, a small planet that orbits the Earth, is much closer to Earth than its Moon. It appears like a dot before a large Sun. There is not a noticeable change in how much sunlight hits Earth during the transit. You might consider visiting the Royal Astronomical Society’s Burlington House courtyard in Piccadilly if you are located near London. There, members of the general public can enjoy the Transit of Mercury with specially-set up telescopes and other astronomical gear. Mercury’s transit – an uncommon event. There are just thirteen to 14 transits per century. The last was in 2006. In Britain, the last such event occurred in 2003.. The next two transits of Mercury will be in 2019, and 2032.. The Royal Astronomical Society says that everyone should have a clear view of next week’s transit. According to the Royal Astronomical Society, “If your telescope is already in use, you should ensure that you are using a high quality filter. This can be used over the objective of the telescope, or in a mirror at the tube’s open end. These filters must be purchased from an accredited astronomical supplier that meets the applicable safety standards. It is not recommended to use the filter located at the end of the eyepiece as the concentrated heat can cause it to crack or melt. (Image: The event will begin at 12: 12 ST and finish at 19: ST. The event will begin at 12: 12 BST and end at ]:42. The RAS states that only a small portion of the Sun’s light is blocked by Mercury because it is so tiny. It is therefore impossible to see Mercury and it can be dangerous to attempt to view it using the naked eye or a telescope without specially-designed filters. RAS holds an event in London To ensure that everyone has the opportunity to enjoy Mercury’s transit in safety, RAS organized a special event at Burlington House Piccadilly London W1J0BQ. The telescopes will be operated by a team of astronomers and astrophysicists. All have been equipped with solar filters that protect the eyes. RAS encourages the public to attend the event on May 9th, when its staff will be available to assist from noon until sunset over nearby buildings. The Royal Academy will host all the equipment including telescopes. The RAS’ lecture theater will host a live stream of Mercury’s transit. In the library, there will be an exhibit of Mercury materials that is a mini-exhibition. The RAS said that both rooms were located on the opposite sides of the courtyard from the telescopes. Satellites to see #Mercury enter spotlight on May 9 cc: @spaceweather @PlanetarioMad — Massimo (@Rainmaker1973) 3 May 2016 Prof. Martin Barstow, President of the RAS, Pro Vice Chancellor and Head of the College of Science and Engineering at the University of Leicester, said: “It is always exciting to see rare astronomical phenomena, such as this transit of Mercury. These observations show that astronomy can be enjoyed by all. According to the RAS, most transits (either starting at sunset or ending at sunrise) can be seen from North America and South America. The eastern half of Asia and the Pacific will also see it. “Observers from eastern Asia, South-Eastern Asia, and Australasia won’t be able see the Transit of Mercury.” Above, Pierre Gassendi, a French astronomer, saw the Transit of Mercury. He is the first person to have seen the event. Image: Wikipedia. Although transits of Mercury occur very rarely, they can be observed from many parts of the globe. The event was first witnessed by Pierre Gassendi (1592-1655), a French scientist, astronomer, philosopher, priest and mathematician in 1631, about twenty years after the invention of the telescope. Louis Mayo is the program manager for NASA’s Goddard Space Flight Center, Greenbelt (Maryland), USA. He said that “Back in 1631,, astronomers only did visual observations using very small telescopes according to today’s standards”. Technology has improved tremendously since those early days. We can now study the Sun, and other planetary transits much more closely. According to the National Aeronautics and Space Administration, “[The transit of Mercury] refers to the passage of a satellite across the Sun’s bright disc. The planet is visible as a tiny black disc slowly moving towards the Sun at this moment. Mercury’s and Venus orbits lie within Earth’s orbit, therefore they can only produce a transit. Solar Projection: This method used to be considered safe before the advent of the solar filter. However, it is now less secure. There is little danger if it’s done correctly. It is possible to view the Sun through your telescope, without any filters. (Image: Why is the planet called Mercury? Mercury was the Roman messenger to the gods. Romans believed the goddesses and gods had control over everything. Mercury, the messenger, had wings attached to his helmet and shoes so he could travel extremely fast from one place to another. Mercury, a planet orbiting the Sun at incredibly high speeds, is also fast. NASA says that Mercury is a small planet. Mercury orbits the Sun in 365 hours, while Earth does so in 88. Mercury’s Transits were very helpful for Astronomers in the Past. Although today there are no scientific reasons to observe Mercury’s transit, many astronomers have used them as a reference point.
