Jupiter, Saturn merging in night sky on Dec 21, closest since Galileo’s time in the 17th century
Cape Canaveral (US), Dec 20: Jupiter and Saturn will merge in the night sky Monday, appearing closer to one another than they have since Galileo's time in the 17th century.
Astronomers say so-called conjunctions between the two largest planets in our solar system aren't particularly rare.
Jupiter passes its neighbour Saturn in their respective laps around the sun every 20 years.
But the one coming up is especially close: Jupiter and Saturn will be just one-tenth of a degree apart from our perspective or about one-fifth the width of a full moon.
They should be easily visible around the world a little after sunset, weather permitting.
Toss in the winter solstice in the Northern Hemisphere, the longest night of the year and the summer solstice in the Southern Hemisphere and this just-in-time-for-Christmas spectacle promises to be one of the greatest of Great Conjunctions.
What is most rare is a close conjunction that occurs in our nighttime sky," said Vanderbilt University's David Weintraub, an astronomy professor.
"I think it's fair to say that such an event typically may occur just once in any one person's lifetime, and I think 'once in my lifetime' is a pretty good test of whether something merits being labeled as rare or special.
It will be the closest Jupiter-Saturn pairing since July 1623, when the two planets appeared a little nearer.
This conjunction was almost impossible to see, however, because of its closeness to the sun.
Considerably closer and in plain view was the March 1226 conjunction of the two planets when Genghis Khan was conquering Asia.
Monday's conjunction will be the closest pairing that is visible since way back then.
Saturn and Jupiter have been drawing closer in the south-southwest sky for weeks. Jupiter bigger and closer to Earth is vastly brighter.
I love watching them come closer and closer to each other and the fact that I can see it with my naked eyes from my back porch! Virginia Tech astronomer Nahum Arav said in an email.
To see it, be ready shortly after sunset Monday, looking to the southwest fairly low on the horizon.
Saturn will be the smaller, fainter blob at Jupiter's upper right. Binoculars will be needed to separate the two planets.
Despite appearances, Jupiter and Saturn will actually be more than 450 million miles (730 million kilometers) apart. Earth, meanwhile, will be 550 million miles (890 million kilometers) from Jupiter.
A telescope will not only capture Jupiter and Saturn in the same field of view, but even some of their brightest moons.
Their next super-close pairing: March 15, 2080.

Karnataka Maritime Board announces plans for Mangaluru Water Metro Project
Mangaluru (Karnataka), Nov 4: After being endowed with multi connectivity facilities like three national highways, port and airport, Mangaluru city is now looking at a significant move towards sustainable urban mobility as the Karnataka Maritime Board (KMB) has announced plans for the Mangaluru Water Metro Project (MWMP), officials said on Monday.
This ambitious initiative aims to transform public transportation in the state, utilising National Waterways to connect areas along the Nethravathi (NW-74) and Gurupura (NW-43) rivers, they said.
Set to become India's second-largest water transport system after Kochi, the project promises an eco-friendly, economical and efficient mode of travel, the officials said.
According to officials, the MWMP will connect isolated communities from Bajal to Maravoor, enhancing accessibility and promoting the holistic development of these regions. The initiative is expected to boost local livelihoods and improve the standard of living through integrated transport networks.
According to the project report available with PTI, the MWMP will be rolled out in phases, with the initial stretch covering 30 kilometres along the Nethravathi and Gurupura river backwaters.
The priority route, beginning at Bajal on the Nethravathi and extending to the Maravoor Bridge on the Gurupura, will feature around 17 modern Metro stations.
Key locations such as Someshwara Temple, Ullal and the New Mangalore Port are included in the proposed route. State-of-the-art electric and diesel catamaran boats will be deployed, equipped with essential amenities to ensure a high standard of comfort and operational efficiency.
A comprehensive Feasibility Report (FR) will assess the project's viability, presenting a detailed cost-benefit analysis, market potential, operational strategies and environmental considerations.
"The report will objectively evaluate the project's merits and challenges, providing crucial information for decision-makers, stakeholders and investors," they said.
Officials in the port and fisheries subdivision told PTI that key areas of analysis has been based on assessing the potential to decongest old port areas, exploring the feasibility of cargo movement using Roll-on/Roll-off (Ro-Ro) water metros, examining water level variations influenced by tidal flows, integration with feeder services to ensure seamless last-mile connectivity, demand forecasts over a 25-year period, based on extensive socio-economic research of usage and utility of the MWMP.
The project's Terms of Reference (ToR) emphasise sustainable development, involving thorough site identification, user demand assessments and environmental impact studies. Comprehensive surveys such as LIDAR mapping, bathymetric studies and topographical analysis will ensure accurate planning and implementation, the officials told.
Furthermore, technical collaborations with national institutes of repute will support studies on wave tranquillity, vessel height clearance and infrastructure recommendations for jetties and repair facilities, they said.
A detailed environmental monitoring programme will assess air and water quality, noise levels and aquatic biodiversity in line with Ministry of Environment, Forest, and Climate Change (MOEF&CC) guidelines, the officials added.
The officials of the Maritime Board said the MWMP promises significant economic and environmental benefits, from easing traffic congestion to reducing air pollution. The project will also explore non-fare revenue streams and develop models to ensure financial sustainability.
A socio-economic impact assessment will measure the project's contribution to regional development, backed by projected revenue from passenger fares and ancillary services, a senior official said.
The Board also aims at championing cleaner and greener transportation and to set a precedent for sustainable urban mobility, positioning Mangaluru as a progressive city that leverages its waterways, he added.
