The ‘Great’ Conjunction of Jupiter and Saturn

  • For the last several days, sky watchers have been captivated by the Great Conjunction between Jupiter and Saturn. The closest pass took place on Monday, December 21, but the spectacle itself began days earlier — and will last until at least Christmas Day.

What’s a great conjunction?

  • A pairing between any pair of planets is a conjunction. Jupiter and Saturn are the two largest planets visible to the naked eye, hence the expression ‘Great Conjunction’. These two align roughly every 20 years, which is relatively rare compared to the alignments of planets closer to the Sun (and which consequently have shorter orbits).

So, why is this conjunction special?

  • This time, Jupiter and Saturn are a tenth of a degree apart viewed from Earth. From some views, that might give them the appearance of converging into one, but viewers around the world have found them distinct enough to tell them apart. Also, the position of Earth matters. Not every alignment provides a clear viewing.

And how rare is this conjunction?

  • The last Great Conjunction happened in 1623. For context, Galileo had discovered four of Jupiter’s moons with his telescope a few years previously — but scientists today believe Galileo would not have found it easy to see the conjunction, because the planets were aligned too close to the Sun from Earth’s perspective. From an Indian context, Jahangir was ruling the Mughal empire at the time, and the Maratha warrior king Chhatrapati Shivaji was yet to be born.
  • The last time the two planets were close enough to be viewed in the night sky was in 1226. This was just a year before the death of the Mongol ruler Genghis Khan.

How long will the spectacle continue?

  • Between December 16 and 25, the distance between the two planets in the sky will appear to a viewer from Earth to be less than the diameter of a full moon.

What if some watchers miss it?

  • The next two conjunctions are in 2040 and 2060, although they will not be as easy to view or as prominent as this one. It’s the big one after that to look out for — on March 15, 2080. That’s 60 years from today, something for younger sky watchers to be optimistic about.

China launched new CZ-8 carrier rocket

  • China successfully test-launched its next-generation CZ-8 (Long March 8) medium-lift carrier rocket
  • The rocket was launched from the Wenchang spacecraft launch site, located in Hainan.
  • The carrier delivered five satellites to orbit.
  • The new rocket is meant to meet the demand for economical, medium-lift, high-frequency commercial missions.
  • It will have non-toxic propellants and take about 10 days of preparation to launch, with a capacity of at least 10 launches each year.
  • A future variant of the CZ-8 – the CZ-8R – will be reusable, putting it on par with the Falcon series made by American aerospace company SpaceX.
