Welcome to the I Can't Sleep podcast, where I read random articles from across the web to bore you to sleep with my soothing voice. I'm your host, Benjamin Boster. Today's episode is from a Wikipedia article titled Eclipse. An Eclipse is an Astronautical. An Eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured by passing into the shadow of another body or by having another body pass between it and the viewer.

This alignment of three celestial objects is known as Sizogy. Apart from Zizigi, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is a result of either an occultation, completely hidden, or a transit partially hidden. The term eclipse is most often used to describe either a solar eclipse when the moon's shadow crosses the Earth's surface or a lunar eclipse when the moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth's moon system. for example a planet moving into the shadow cast by one of its moons

a moon passing into the shadow cast by its host planet or a moon passing into the shadow of another moon a binary star system can also produce eclipses if the plane of the orbit of its constituent stars intersects the observer's position for the special cases of solar and lunar eclipses These only happen during an eclipse season, the two times of each year when the plane of the Earth's orbit around the sun crosses the plane of the moon's orbit around the Earth. The type of solar eclipse that happens during each season, whether total, annular, hybrid, or partial, depends on apparent sizes of the sun and moon. If the orbit of the Earth around the Sun and the Moon's orbit around the Earth were both in the same plane with each other,

and eclipses would happen each and every month. There would be a lunar eclipse at every full moon and a solar eclipse at every new moon. And if both orbits were perfectly circular, then each solar eclipse would be the same type every month. It is because of the non-planner and non-circular differences that eclipses are not a common event. Lunar eclipses can be viewed from the entire,

entire nightside half of the earth, but solar eclipses, particularly total eclipses, occurring at any one particular point on Earth's surface, are very rare events that can be many decades apart. Etymology The term is derived from the ancient Greek noun eclipsis, which means the abandonment, the downfall, or the darkening of a heavenly body, which is derived from the verd eclipo, which means to abandon, to darken, or to cease to exist, a combination of prefix eck from preposition eck, and a verb lipo to be absent.

Umbra, penumbra, and entumbra. For any two objects in space, a line can be extended from the first through the second. The latter object will block some amount of light being emitted by the former, creating a region of shadow around the axis of the line. Typically, these objects are moving with respect to each other and their surroundings, so the resulting shadow will sweep through a region of space, only passing through any particular location in the region for a fixed interval of time.

As viewed from such a location, the shadowing event is known as an eclipse. Typically, the cross-section of the objects involved in an astronomical eclipse are roughly disk-shaped. The region of an object's shadow during an eclipse is divided into three parts. The umbra, within which the object completely covers the light source, for the sun the light source is the photosphere. The antumbra, extending beyond the tip of the umbra,

within which the object is completely in front of the light source, but too small to completely cover it. The panumbra, within which the object, which is only partially in front of the light source. A total eclipse occurs when the observer is within the umbra, an annular eclipse when the observer is within the antumbra, and a partial eclipse when the observer is within the penumbra. During a lunar eclipse, only the umbra and panumbra are applicable.

This is because Earth's apparent diameter from the viewpoint of the moon is nearly four times that of the sun. The same terms may be used. used analogously in describing other e.g. the antumbra of Dimos crossing Mars, or Phobos entering Mars's bonumbra. The first contact occurs when the eclipsing object's disk first starts to impinge on the light source. Second contact is when the disc moves completely within the light source. Third contact when it starts to move out of the light. And fourth or last contact when it finally leaves the light sources disk entirely. Eclipse cycles. An eclipse cycle takes place when eclipses in a series

are separated by a certain interval of time. This happens when the orbital motions of the bodies form repeating harmonic patterns. A particular instance is the Saros, which results in a repetition of a solar or lunar eclipse every 6,585.3 days, or a little over 18 years. Because this is not a whole number of days, successive eclipses will be visible from different parts of the world. Earth-moon system An eclipse involving the sun, earth, and moon can occur only when they are nearly in a straight line,

allowing one to be hidden behind another, viewed from the third. Because the orbital plane of the moon is tilted with respect to the orbital plane of the Earth, the ecliptic, Eclipses can occur only when the moon is close to the intersection of the two planes, the nodes. The sun, earth, and nodes are aligned twice a year during an eclipse season. An eclipse can occur during a period of about two months around these times. There can be from four to seven eclipses in a calendar year, which repeat according to various eclipse cycles, such as Osaros.

Between 1901 and 2100, there are the maximum of seven eclipses in four penumbral lunar and three solar eclipses, 1908, 2038, four solar and three lunar eclipses, 1918, 1973, 2004, five solar and two lunar eclipses, 1934. excluding penumbral lunar eclipses, there are a maximum of seven eclipses in 1591, 1656, 1787, 1805, 1918, 1935, 1982, and 2094. Solar eclipse. As observed from the Earth, a solar eclipse occurs when the moon passes in front of the sun. The type of solar eclipse, event depends on the distance of the moon from the earth during the event. A total solar eclipse occurs when the earth intersects the Umbra portion of the moon's shadow. When the Umbra does not reach the surface of the earth, the sun is only partially occulted,

resulting in an annular eclipse. Partial solar eclipses occur when the viewer is inside the penumbra. The eclipse magnitude is the fraction of the sun's diameter that is covered by the moon. For a total eclipse, this value is always greater than or equal to one. In both annular and total eclipses, the eclipse magnitude is the ratio of the angular sizes of the moon to the sun. Solar eclipses are relatively brief events that can only be viewed in totality along a

relatively narrow track. Under the most favorable circumstances, a total solar eclipse can last for 7 minutes 31 seconds and can be viewed along a track that is up to 250 kilometers wide. However, the region where a partial eclipse can be observed is much larger. The moon's Umbra will advance eastward at a rate of 1,700 kilometers per hour until it no longer intersects the Earth's surface. During a solar eclipse, the moon can sometimes perfectly cover the sun because its apparent size is nearly the same as the suns when viewed from the earth. A total solar eclipse is in fact an occultation, while an annular solar eclipse is a transit.

When observed at points in space other than from the earth's surface, a sun can be eclipsed by bodies other than the moon. Two examples include when the crew of Apollo 12 observed. the Earth to eclipse the Sun in 1969, and when the Cassini probe observed Saturn to eclipse the Sun in 2006. Lunar eclipse. Lunar eclipses occur when the moon passes through the Earth's shadow. This happens only during a full moon when the moon is on the far side of the Earth from the sun. Unlike a solar eclipse, an eclipse of the moon can be observed from nearly an entire hemisphere. For this reason, it is much more common to observe a lunar eclipse from a given location. A lunar eclipse lasts longer, taking several hours to complete, with totality itself usually averaging

anywhere from about 30 minutes to over an hour. There are three types of lunar eclipses. Penumbral, when the moon crosses only the Earth's panumbra. Partial, when the moon crosses partially into the Earth's umbra. and total when the moon crosses entirely into the Earth's Umbra. Total lunar eclipses pass through all three phases. Even during a total lunar eclipse, however, the moon is not completely dark. Sunlight refracted through the Earth's atmosphere enters the umbra and provides a feigned illumination.

Much as in a sunset, the atmosphere tends to more strongly scatter light with shorter wavelengths. So the illumination of the moon by refracted light has a red hue. Thus the phrase blood moon is often found in descriptions of such lunar events as far back as eclipses are recorded. Historical record Records of solar eclipses have been kept since ancient times. Eclipse dates can be used for chronological dating of historical records. A Syrian clay tablet in the Ugaritic language records a solar eclipse. which occurred on March 5, 1223 BC. While Paul Griffin argues that a stone in Ireland records an eclipse on November 30th, 3,340 BC,

positing classical era astronomers' use of Babylonian eclipse records, mostly from the 13th century BC, provides a feasible and mathematically consistent explanation for the Greek finding all three lunar mean motions. synotic, anomalistic, trichonitic, to a precision of about one part in a million or better. Chinese historical records of solar eclipses date back over 3,000 years, and have been used to measure changes in the Earth's rate of spin. By the 1600s, European astronomers were publishing books with diagrams explaining how lunar and solar eclipses occurred. In order to disseminate this information to a broader audience and decrease fear of the consequences of eclipses, booksellers printed broadsides explaining the event either using the science or via astrology. Other planets and dwarf planets.

Gas giants The gas giant planets have many moons and thus frequently display eclipses. The most striking involved Jupiter, which has four large moons, moons and a low axial tilt, making eclipses more frequent as these bodies pass through the shadow of the larger planet. Transits occur with equal frequency. It is common to see the larger moons casting circular shadows upon Jupiter's cloud tops. The eclipses of the Galilean moons by Jupiter became accurately predictable once their orbital elements were known. During the 1670s, it was discover that these events were occurring about 17 minutes later and expected when Jupiter was on the

far side of the sun. Whole rumor deduced that the delay was caused by the time needed for light to travel from Jupiter to the Earth. This was used to produce the first estimate of the speed of light. On the other three gas giants, Saturn, Uranus, and Neptune, eclipses only occur at certain periods during the planet's orbit, due to their high inclination between the orbits of the moon and the orbital plane of the planet. The moon Titan, for example, has an orbital plane tilted about 1.6 degrees to Saturn's equatorial plane. But Saturn has an axial tilt of nearly 27 degrees.

The orbital plane of Titan only crosses the line of sight to the sun at two points along Saturn's orbit. as the orbital period of Saturn is 29.7 years, an eclipse is only possible about every 15 years. The timing of the Jovian satellite eclipses was also used to calculate an observer's longitude upon the earth. By knowing the expected time when an eclipse would be observed at a standard longitude, such as Greenwich, the time difference could be computed by accurately observing the local time of the eclipse. The time difference gives the longitude of the observer because every hour of difference corresponded to 15 degrees around the Earth's equator. This technique was used, for example, by Giovanni di Cassini in 1679 to remap France.

Mars On Mars, only partial solar eclipses, transits, are possible because neither of its moons is large enough at their respective orbital radii. to cover the sun's disc as seen from the surface of the planet. Eclipses of the moons by Mars are not only possible but commonplace, with hundreds occurring each Earth year. There are also rare occasions when Dimos is eclipsed by Phobos. Martian eclipses have been photographed from both the surface of Mars and from orbit.

Pluto Pluto, with its proportionately largest moon Karon, is also the site of, of many eclipses. A series of such mutual eclipses occurred between 1985 and 1990. These daily events led to the first accurate measurements of the physical parameters of both objects. Mercury and Venus Eclipses are impossible on Mercury and Venus, which have no moons. However, both have been observed to transit across the face of the sun. There are on average 13 transits of Mercury each century.

Transits of Venus occur on pairs separated by an interval of eight years, but each pair of events happen less than once a century. According to NASA, the next pair of transits will occur on December 10th, 2117, and December 8th, 2125. Transits on Mercury are much more common. Eclipsing binaries A binary star system consists of two stars that, orbit around the common center of mass.

The movements of both stars lie on a common orbital plane in space. When this plane is very closely aligned with the location of an observer, the stars can be seen to pass in front of each other. The result is a type of extrinsic variable star system called an eclipsing binary. The maximum luminosity of an eclipsing binary system is equal to the sum of the luminosity contributions from the individual stars. When one star passes in front of the other, the luminosity of the system is seen to decrease.

The luminosity returns to normal once the two stars are no longer in alignment. The first eclipsing binary star system to be discovered was Algol, a star system in the constellation Perseus. Normally, this star system has a visual magnitude of 2.1. However, every 2.867 days, the magnitude decreases to 3.4 for more than 9 hours. This is caused by the passage of the dimmer member of the pair in front of the brighter star.

A concept that an eclipsing body caused these luminosity variations was introduced by John Goodrick in 1783. Types Sun, Moon, Earth, Solar Eclipse. Anular eclipse, hybrid eclipse, partial eclipse.
