The goal was to measure the AU then, knowing the orbital speeds of all the other planets round the Sun, the scale of the Solar System would fall into place. However, Halley realised that Mercury was so far away that its parallax angle would be very difficult to determine. But no-one had found a way to calculate accurate distances to the planets from the Earth. Johannes Kepler, in the early 17 th century, had shown that the distances of the planets from the Sun governed their orbital speeds, which were easily measurable. Halley was aware that the AU was one of the most fundamental of all astronomical measurements. This distance is known as the astronomical unit’ or AU. Calculating this angle would allow astronomers to measure what was then the ultimate goal: the distance of the Earth from the Sun. By timing the transit from two widely-separated locations, teams of astronomers could calculate the parallax angle - the apparent difference in position of an astronomical body due to a difference in the observer’s position. He realised that, from different latitudes, the passage of the planet across the Sun’s disc would appear to differ. In November 1677, Halley observed a transit of the innermost planet, Mercury, from the desolate island of St Helena in the South Pacific. And you can put it all down to the extraordinary polymath Edmond Halley. They were based at a girls’ school, where - it is alleged - the combined forces of three schoolmistresses outperformed the professionals with the accuracy of their observations.įor centuries, transits of Venus have drawn explorers and astronomers alike to the four corners of the globe. On that occasion, the American astronomer Professor Simon Newcomb led a party to South Africa to observe the event. This ‘transit’ of Venus was the first since 6 December 1882. For over six hours, the planet Venus steadily inched its way over the surface of the Sun. On 8 June 2004, more than half the population of the world were treated to a rare astronomical event. Transits have helped shape our view of the whole Universe, as Heather Cooper and Nigel Henbest explain "Virat Kohli has a better range of shots as compared to Babar Azam, but he also has one area of weakness," Javed had said.June 2004 saw the first passage, known as a ‘transit’, of the planet Venus across the face of the Sun in 122 years. Javed had stirred a debate earlier this week when he had said that India captain Virat Kohli can learn from Pakistan limited-overs skipper Babar Azam to improve on batting technique. While Afridi has 48 Test wickets, 51 ODI wickets and 25 T20I scalps, Bumrah has taken 83 wickets in Tests, 108 in ODIs and 59 in T20Is. "In fact, Shaheen is a better bowler than Bumrah with the new ball." "I think they are equally good with the new ball, but Shaheen can improve his death bowling," he added. I think he is slightly ahead of Shaheen when it comes to death bowling," Javed told Cricket Pakistan channel on YouTube. Bumrah, who first played for India in 2016, has played 19 Tests, 67 ODIs and 50 T20Is. Shaheen, a left-arm fast bowler, has played 15 Tests, 25 ODIs and 23 T20Is for Pakistan since his international debut in 2018.
Javed said while India's Bumrah is a better fast bowler than Pakistan's Shaheen at the death, both pacers are "equally good" in bowling with the new ball, before adding that Shaheen is a better new ball bowler than his Indian counterpart. Former Pakistan fast bowler Aaqib Javed said Shaheen Afridi is a better bowler than Jasprit Bumrah with the new ball.
