Transit of Mercury CHEOPS and Exoplanets

Sacred Space Astronomy avatarPosted on November 22, 2019 by Deirdre KelleghanNovember 22, 2019

Drawing Yes, indeed I felt lucky to see the transit of mercury on November 11th. Black clouds full of heavy rain were in constant supply all morning. My PST telescope and drawing materials were in and out in the hope of a break in the weather. It was my intention to use the drawing to help explain the transit of Mercury, CHEOPS and Exoplanets. As you can see from the drawing above (which is not rotated) I got my first view of the tiny planet at 12:51. I sketched one black dot on top of my previously drawn solar disc. Then the rain bucketed down like rods with a big wind attached. Next chance came at 13:33 a second black dot added to the effort. Then it rained cats and dogs till 14:26 when my final opportunity gave me a third mercury dot to add to the sketch.  Most Irish observers had a similar story and images of this unique … Continue reading →

Across the Universe: New Worlds

Sacred Space Astronomy avatarPosted on June 20, 2019 by Br. Guy ConsolmagnoJune 11, 2019
This entry is part 28 of 191 in the series Across the Universe

First published in The Tablet in June, 2007; we published it here in 2015 In early 2007, a team lead by Stéphane Udry of the Geneva Observatory announced the discovery around the red dwarf star Gliese 581 of a planet that is only eight times the mass of Earth and about 50 per cent bigger in radius. Orbiting close to its sun, its year is less than two weeks long; but because that star is so small and dim compared to ours, temperatures on the planet should range between zero and 40 degrees Celsius (about 30 to 100 Fahrenheit). Room temperature. Water should be liquid there, perhaps covering its surface with oceans ripe for life. At least, I hope it’s covered in oceans. Swimming would be easier than walking on a planet where the gravity is three and a half times that of Earth. The star is only 20 light years away from us; robot spaceships in the next 100 years … Continue reading →

Kepler Space Telescope End of Mission

Sacred Space Astronomy avatarPosted on November 13, 2018 by Bob TrembleyNovember 13, 2018

After nine years in deep space collecting data that indicate our sky to be filled with billions of hidden planets – more planets even than stars – NASA’s Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life. “As NASA’s first planet-hunting mission, Kepler has wildly exceeded all our expectations and paved the way for our exploration and search for life in the solar system and beyond,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington. “Not only did it show us how many planets could be out there, it sparked an entirely new and robust field of research that has taken the science community by storm. Its discoveries have shed a new light on … Continue reading →

Across the Universe: Feeding Curiosity

Sacred Space Astronomy avatarPosted on October 5, 2017 by Br. Guy ConsolmagnoMay 30, 2018
This entry is part 145 of 191 in the series Across the Universe

This column first ran in The Tablet in October 2012 Finally [in 2012!], a planet has been discovered orbiting Alpha Centauri. That star, a neighbor of the Southern Cross, is actually a triplet of stars orbiting each other – as first discovered by a Jesuit missionary, Fr. Jean Richaud, some 300 years ago. And it’s is our nearest neighbor, merely four and a half light years away. Granted, the new planet orbits so close to its star (the middle member of the triplet) that its surface would be hotter than molten lava. But its existence gives hope that Alpha Centauri could also host another planet at a more temperate location, which we just haven’t seen yet. Unlike other detected planetary systems, you could actually envision a conversation with hypothetical intelligences inhabiting such a hypothetical planet; the conversation lag would be a mere nine years between exchanges. Could we go there? Half a century ago, it took Apollo about a week … Continue reading →

Across the Universe: Myriad planets

Sacred Space Astronomy avatarPosted on August 31, 2017 by Br. Guy ConsolmagnoMay 30, 2018
This entry is part 140 of 191 in the series Across the Universe

This column first ran in The Tablet in September 2012 One hundred thousand planets. That’s the census we can infer for just one corner of the Milky Way Galaxy being watched by the Kepler space telescope, according to results presented [August 2012] at the International Astronomical Union in Beijing. Watching each of 145,000 stars in a bit of the Milky Way about 10 degrees wide over many years (three and a half years, [as of that time]), Kepler is looking for faint dips in brightness occurring on a regular basis that can be attributed to the passage, a “transit”, of a planet in front of that star. So far some 2300 candidate planets have been identified. (Many stars have more than one candidate.) But in order for us to see such a blip, the planet’s orbit must be lined up almost exactly between the star and us; we’re missing any planets whose orbits are tilted above or below their star … Continue reading →

Across the Universe: Super Earths

Sacred Space Astronomy avatarPosted on August 24, 2017 by Br. Guy ConsolmagnoMay 30, 2018
This entry is part 139 of 191 in the series Across the Universe

126This column first ran in The Tablet in August 2015 Half the planets in our solar system are relatively small, rocky, and found near our sun. The other half are all significantly bigger, covered in giant atmospheres, and orbit far away from the sun. Explaining this trend in size and orbits is simple. If the planets formed from a disk of gas and dust (we’ve actually observed such disks around young stars) then planets forming farther from the sun are colder. If they’re far enough from the sun that water in the gas freezes into ice, they’ll jump up in size — a gas cloud has twice as much water as rocky material to snowball into a planet. And once a planet reaches a critical size, it captures gas from the nebula to make a thick atmosphere. So, inner rocky planets stay small; but once the icy outer planets get big enough, they jump up to even larger sizes. The … Continue reading →

Across the Universe: Me and My Shadows

Sacred Space Astronomy avatarPosted on April 14, 2016 by Br. Guy ConsolmagnoMay 30, 2018
This entry is part 69 of 191 in the series Across the Universe

This column first appeared in The Tablet in April, 2009. Last week [April 2009], NASA’s Kepler space telescope sent back its first images of a star field in the constellation Cygnus. Launched in March [2009], Kepler has been slowly positioning itself far from Earth’s bright clouds; unlike most spacecraft, it’s not a man-made moon orbiting the Earth, but a man-mad asteroid following the Earth around the Sun, with a “year” a few weeks longer than Earth’s. Now, from the darkness of its orbit, it has aimed its telescopes at the Milky Way to look for traces of Earth-like planets. The plan is simple. For the next three years (six years, if all goes well) it will be watching the same star-filled region of the Milky Way, carefully measuring the brightness of every star in its field of view – some 100,000 of them – looking to see if any one of them periodically dims by a hundredth of a percent or less. … Continue reading →

Misinformative Books from Surprising Places

Misinformation.  It is a big topic these days, and a big problem.  And when the topic is astronomy and the Copernican Revolution, misinformation abounds, even in the relatively durable, more controlled medium of books.  “Caveat lector!” applies to this topic—“Let the reader beware!” Two recently-published books are especially disappointing in … Continue reading…

This week, the Moon appears in the predawn sky, Mars is in a close conjunction with the Pleiades star cluster, and the planets Mercury, Jupiter and Saturn appear low above the horizon before dawn; Mercury and Jupiter appear in a very close conjunction – less than 1 degree apart, as they swap positions over the course of several days.
