1. Planets have magnetic field around them because of the liquid iron in their cores. As the planets rotate, so the iron swirls, generating electric currents that create the magnetic field

52. Earth’s atmosphere is the only atmosphere discovered till date that human can breathe in.

53. Earth’s atmosphere was formed from gases pouring out from volcanoes.

54. Jupiter has no surface for a spacecraft to land on because it is made mostly from helium gas and hydrogen. The massive pull of Jupiter’s gravity squeezes the hydrogen so hard that it is liquid.

55. Jupiter spins right round in less than 10 hours which means that the planet’s surface is moving at nearly 50,000 km/hr.

56. The first successful planetary space probe was the USA’s Mariner 2, which flew past Venus in 1962.

57. Voyager 2 has flown over 6 billion km and is heading out of the solar system after passing close to Neptune in 1989.

58. To save fuel on journeys to distant planets, space probes may use a nearby planet’s gravity to catapult them on their way. This is called slingshot.

59. Hubble’s law showed that Universe is getting bigger – and so must have started very small. This led to the idea of Big Bang.

60. It’s believed that it was the impact of a big meteorite may have chilled the earth and wiped out all the dinosaurs.

61. The first astronomers thought the regular pulses from far space might be signals from aliens, and pulsars were jokingly called LGMs (short for Little Green Men).

62. Pulsars probably result from a supernova explosion – that is why most are found in the flat disc of the Milky Way, where supernovae occur.

63. Three moons have yet been found to have their own moons: Saturn’s moon Titan, Jupiter’s Lo, and Neptune’s Triton.

64. The largest moon in the Solar System is the Jupiter’s moon Ganymede.

65. Saturn is not solid, but is made almost entirely of gas – mostly liquid hydrogen and helium. Only in the planet’s very small core is there any rock.

66. Winds ten times stronger than a hurricane on Earth swirl around Saturn’s equator reaching up to 1100 km/h – and they never let up: even for a moment.

67. The first space station was the Soviet Salyut 1 launched in April 1971; its low orbit meant it stayed up only five months.

68. In April 2001, Dennis Tito became the first space tourist, ferried up to the ISS by the Russian Soyuz space shuttle.

69. Einstein’s theory of general relativity shows that gravity not only pulls on matter, but also space and even ‘Time’ itself.

70. Since the star Deneb is 1800 light years away, we see it as it was when the emperor Septimus Severius was ruling the Rome (AD 200).

71. With powerful telescopes, astronomers can see galaxies 2 billion light years away. This means we see them as they were when the only life forms in Earth were bacteria.

72. The slowest rotating planet is Venus, which takes 243.01 days to turn around.

73. The fastest spinning objects in the Universe are neutron stars – these can rotate 500 times in just 1 second.

74. In summer in Uranus, the sun does not set for 20 years. In winter, darkness lasts for 20 years. In autumn, the sun rises and sets every 9 hours.

75. Uranus’s moon Miranda is the weirdest moon of all. It seems to have been blasted apart, and then put together again

76. Solar flares reach temperatures of 10 million °C and have the energy of a million atom bombs.

77. True binary stars are two stars held together by one another’s gravity, which spend their lives whirling around together like a pair of dancers.

 

78. Halley predicted that a comet he had discovered would return in 1758, 16 years after his death, and it really did. It was the first time a comet’s arrival had been predicted, and the comet was named after him as Halley’s Comet.

79. Ceres is the biggest asteroid in the Solar System – 940 km across, and 0.0002% the size of the earth.

80. The sun is about 5 billion years old and half a way through its life – as a medium sized star it will probably live for around 10 billion years.

81. Neptune’s mood Triton is the coldest place in the Solar System, with surface temperatures of -236°C.

82. Voyager 2 will beam back data until 2020 as it travels beyond the edges of the Solar System.

83. The Pioneer 10 and 11 probes carry metal plaques with messages for aliens telling them about us.

84. Einstein’s theory of Special Relativity (1905) shows that all measurements are relative, including time and speed. In other words, time and speed depends upon where you measure them.

85. When things are falling, their acceleration cancels out gravity, which is why astronauts in orbits are weightless.

86. The first space telescope was the Copernicus, sent out in 1972.

87. Astronauts learn Scuba diving which helps them to deal with space walks.

88. Weightlessness makes astronauts grow several centimeters during a long mission.

89. The first living creature in space was the dog Laika on – board Sputnik 2 in 1957. Sadly, she died when the spacecraft’s oxygen supply ran out.

90. The first manned space flight was made in April 1961 by the Soviet Cosmonaut, Yuri Gagarin in Vostok 1.

91. The heart of a star reaches 16 million °C. A grain of sand this hot would kill someone 150 km away.

92. Stars twinkle because we see them through the wafting of the atmosphere.

93. The sun weighs 2,000 trillion trillion tones – about 300,000 times as much as the Earth – even though it is made almost entirely of hydrogen and helium, the lightest gases in the Universe.

94. The sun gets hot because it is so big that the pressure in its core is so tremendous – enough to force the nuclei of hydrogen atoms to fuse to make helium atoms. This nuclear reaction is like a gigantic atom bomb and it releases huge amounts of heat.

95. The nuclear fusion reactions in the Sun’s core send out billions of light photons every minute but they take 10 million years to reach its surface.

96. The Hiroshima bombs released 84 trillion joules of energy. A supernova releases 125,000 trillion trillion times as such.

97. The most distant galaxies (quasars) have red shifts so big that they must be moving away from us at speeds approaching the speed of light.

98. When light waves from distant galaxies are stretched out his way, they look redder. This is called red shift.

99. The moon’s gravity is 17% of the Earth’s so astronauts in space suits can jump 4 m high on the moon.

100. The moon is the only other world that humans have set foot on. Because the moon has no atmosphere or wind, the footprints planted in its dusty surface in 1969 by the Apollo astronauts are still there today, perfectly preserved.

101. On the moon’s surface are large dark patches called seas – because this is what people once believed they were. They are, in fact, lava flows from ancient volcanoes.

102. Quasars are the most distant known objects in the Universe. Even the nearest is billions of light years away.

103. The brightest quasar is 3C 273, 2 billion light years away.

104. The brightest stars in the night sky are not actually stars, but the planets Jupiter, Venus, Mars and Mercury.

105. Jupiter’s moon Europa may have oceans of water beneath its dry surface and it is a major target in the search for life in the Solar System.

106. There may be 20 trillion galaxies in the Universe.

107. Galaxies are often found in a group or clusters. One cluster may have 30 or so galaxies in it.

108. In the 1970s the US Vikings 1 and 2 and the Soviet Mars 3 and 5 probes all reached the surface of Mars.

109.  The Solar System has nine planets including Pluto, but Pluto may be an escaped moon or an asteroid not a planet.

110. The Milky Way belongs to a cluster of 30 galaxies called the Local Group, which is 7 million light years across.

111. The Virgo Cluster is 50 million light years away and is made up of 1000 galaxies.

112. For a satellite or a spacecraft to stay in orbit 200 km above the earth, it has to fly over 8 km/sec.

113. When a spacecraft reaches 140% of the orbital velocity i.e. 11.2 km/sec, it is going fast enough to break free of the Earth’s gravity. This is called escape velocity

 

Very interesting facts from Astronomers & Scientists.. I still could not get it about fact number 18 ? Half of the stars are visible at daylight with naked eye from Earth? Could anyone explain!
