Seeing the Sun’s corona in the suddenly darkened daytime sky is an experience so compelling that several thousand 'eclipsophiles' will travel around the world to see any total solar eclipse they reasonably can.Īnd to make that planning a little easier, Sky & Telescope is proud to announce its newest product: a 12-inch globe of Earth embellished with the track of every total and hybrid solar eclipse through the end of this century. I sure hope so! Total solar eclipses are nature's most spectacular sky sights. So are they really planning when and where to stand in the Moon's shadow again? got a chance to witness totality on August 21, 2017, and most of them were indeed seeing the Sun's corona for the first time. There's a saying that goes: 'Once you've seen your first total solar eclipse, your first four words are 'When's the next one?'' Millions of skywatchers all across the U.S. The question of whether we are alone could melt away for good.This 12-inch globe shows the paths of every total and hybrid solar eclipse from 2001 to 2100. Its many hoped-for discoveries promise to sharpen, and possibly revolutionize, astronomy, physics and philosophy. The Webb telescope will search for the origins of the universe and the elemental stew of life. Four hundred years ago came the first telescopes 52 years ago, humans landed and walked on the moon.

Humanity has always been beset by one calamity or another, and humans have forever looked up at the stars for answers. The telescope is so smooth that it has been likened to an entire continent that features only fist-sized dimples. The level of precision is hard to fathom. There are in-flight challenges, repeatedly tested on Earth. Canada also produced two important components of the telescope: first, the fine guidance sensor, to keep the telescope fixed on target and second, the near-infrared imager and slitless spectrograph, which helps explore nearby solar systems. Among them is a University of Montreal physicist who will examine TRAPPIST-1 planets. Canadian scientists will lead or co-lead a 10th of the telescope’s first cycle of projects. It is there, and throughout the Webb project, that Canada contributes. Part of Aquarius, for the astrologically minded. A few of the most promising orbit the star TRAPPIST-1, a hop, skip and a jump away, a bit less than 40 light-years. In 2010-11, the Kepler space telescope saw the first rocky planet outside this solar system, a mere 560 light-years away. The Webb will try to discern variations of light that could show “biosignature gases” in an atmosphere – a testament to life. But the other mission that has a shot to make us rethink life as we know it is to stare at rocky planets that seem similar to ours. It will also gaze closer to home at planets such as Neptune. Looking even further back is the first of the Webb telescope’s four primary missions. It was a picture of the past never before imagined. The result – the Hubble Deep Field – revealed a “bewildering variety” of primordial galaxies. For 100 hours, the Hubble turned to look at nothing – a sliver of darkness. The Hubble unveiled glorious images and, in 1995, propelled humanity’s understanding of the universe’s formation. Launched in 1990, with its focus adjusted by astronauts in 1993, the Hubble is an optical telescope in orbit 600 kilometres above the Earth. The Webb telescope picks up where the Hubble Space Telescope left off. The wavelengths of once-visible light stretched out into electromagnetic radiation over their long journey from the universe’s ancient past to our present. The goal is to absorb light emitted from the first stars and galaxies as they formed 13.6 billion or so years ago, and as far back as 100 million years after the Big Bang. This requires something colder than the worst of Canadian winter: -223 C. The gold-plated telescope, 6.5 metres in diameter, will be a collector of infrared light, invisible to the eye but felt as heat.

It will be close enough to easily keep touch with Earth, draw on solar power, and, with a five-layer sunshield of human-hair-thin plastic, keep itself chilled out. Gravity of Earth and sun will help keep the telescope in position.
