Nicholas Copernicus was the astronomer who, five centuries ago, explained that Earth revolves around the Sun, rather than vice versa. A true Renaissance man, he also practised as a mathematician, engineer, author, economic theorist and medical doctor.

Nicholas Copernicus was the astronomer who, five centuries ago, explained that Earth revolves around the Sun, rather than vice versa. A true Renaissance man, he also practised as a mathematician, engineer, author, economic theorist and medical doctor. Upon his death in 1543 in Frombork, Poland, Copernicus was buried in the local cathedral. Over the subsequent centuries, the location of his grave was lost to history.

Who was Copernicus?

  • After his father’s death, Copernicus’s uncle assumed responsibility for his education.
  • The young scholar initially studied at the University of Kraków between 1491 and 1494, and later at Italian universities in Bologna, Padua and Ferrara.
  • In 1519, Copernicus also introduced the concept now known as Gresham’s law, a monetary principle addressing the circulation and valuation of money.

The Copernican model of the universe

  • The cornerstone of Copernicus’s contributions to science was his revolutionary model of the universe.
  • Contrary to the prevailing Ptolemaic model, which maintained that Earth was the stationary centre of the universe, Copernicus argued that Earth and other planets revolve around the Sun.

The search for Copernicus


The Frombork Cathedral serves as the final resting place of more than 100 people, most of whom lie in unnamed graves. There were several unsuccessful attempts to locate Copernicus’s remains, dating as far back as the 16th and 17th centuries. Another failed attempt was made by the French emperor Napoleon after the 1807 Battle of Eylau. Napoleon held Copernicus in high regard as a polymath, mathematician and astronomer.

  • They were guided by the theory of historian Jerzy Sikorski, who claimed that Copernicus, serving as the Canon of Frombork Cathedral, would have been buried near the cathedral altar for which he was responsible during his tenure.
  • This particular skeleton was identified as the closest match to that of Copernicus.

Forensic science

  • In addition to morphological studies, DNA analysis is often used for the identification of historical or ancient remains.
  • In the case of the presumed remains of Copernicus, a genetic identification was possible due to the well-preserved state of the teeth.

An unlikely find

  • An astronomical reference book used by Copernicus for many years was found to contain hair among its pages.
  • This book had been taken to Sweden as war booty following the Swedish invasion of Poland in the mid-17th century.
  • A meticulous examination of the book revealed several hairs, thought likely to belong to the book’s primary user, Copernicus himself.

Larger and more frequent solar storms will make for potential disruptions and spectacular auroras on Earth

Retrieved on: 
Saturday, December 30, 2023

Longer nights during the fall and winter also favour seeing more auroras, but the show is best outside of light-polluted cities.

Key Points: 
  • Longer nights during the fall and winter also favour seeing more auroras, but the show is best outside of light-polluted cities.
  • Impressive auroral events allowed bright auroras to be seen as far south as the United States recently.
  • The number of auroras is increasing as the sun’s activity becomes stronger, approaching a solar maximum.

Night visions

  • The Earth, in the sun’s outer atmosphere, is surrounded by hot magnetic plasma which rushes past us at speeds of several hundred kilometres per second in a flow called the solar wind.
  • Earth has a magnetic field, which protects us from the solar onslaught, but is pushed back by it as well.
  • This explains why auroras are seen at night: not only is it dark, but the sun’s energy takes an indirect route by first being stored in the magnetotail.
  • If the magnetic fields change rapidly, they can affect large regions of the Earth, building up to cause problems for power networks.

Solar cycles

  • About 300 years later, American astronomer George Hale showed that sunspots had intense magnetic fields, several thousand times stronger than Earth’s.
  • In the 400 years since Galileo’s observations, we have found that the number of sunspots varies dramatically over an 11-year long cycle.

Energy storage

  • Magnetic fields store energy, and sometimes, as in Earth’s magnetotail or near sunspots, this energy can be changed to other forms.
  • In the strong fields of sunspots, it can be released as X-rays in rapid, unpredictable flares.
  • Sunspots and flares are near the surface or light-emitting layer of the sun, but material can escape from the sun’s strong gravity field.

Space weather forecasts

  • However, in this, the following solar cycle, we have already exceeded predicted numbers of sunspots and had large magnetic storms, so predictions may need to be revised upward.
  • Although direct measurement of incoming disturbances by satellites in the solar wind gives us only about an hour’s warning of stormy space weather, we can also predict a bit further in advance by watching sunspots rotate into view as the sun turns.

Rare storms

  • The strongest flare of Solar Cycle 25 so far occurred on Dec. 14, and was the most powerful eruption the sun has produced since the great storms of September 2017.
  • Large solar storms are rare, but we must calmly prepare for possible space weather impacts that should maximize in a few years.

Six space missions to look forward to in 2024

Retrieved on: 
Saturday, December 30, 2023

It’s going to be a bumper time for space missions in 2024 – especially to the Moon, our nearest neighbour.

Key Points: 
  • It’s going to be a bumper time for space missions in 2024 – especially to the Moon, our nearest neighbour.
  • Rather than peering through telescopes to look at the stars, I prefer to see them in a vial in my lab.
  • So it was a great delight to see the safe return of Nasa’s Osiris-Rex mission from asteroid (101955) Bennu in September 2023.

CLPS missions

  • Nasa’s series of Commercial Lunar Payload Service (CLPS) missions, many of which will launch in 2024, are set to bring a variety of instruments to the Moon.
  • The CLPS programme is part of Nasa’s Artemis initiative to continue human exploration of the Moon.
  • CLPS-2 is timetabled to launch in early January 2024, and there are four other CLPS missions planned for launch throughout the year.

Trailblazer


Continuing the lunar theme, Nasa’s Trailblazer mission travels to the Moon to understand where any water is situated. Is it locked inside rock as part of the mineral structure, or is it deposited as ice on the rocky surface? Trailblazer is currently scheduled for launch in the first quarter of 2024. However, no precise date has been confirmed. It’s a small mission, part of the Artemis human lunar exploration programme.

Chang'e 6

  • This is particularly significant because the spacecraft will collect material from the lunar farside – the South Pole Aitkin Basin.
  • This is a region where it is believed there is abundant frozen water.

Hera


In September 2022, Nasa’s Dart mission encountered a system consisting of two asteroids called Didymos and Dimorphos, and crashed into Dimorphos (the junior partner). The impact had a purpose: to see if such a collision could divert the asteroid in its path – a necessary goal if ever Earth were to be the target of a direct hit by an incoming asteroid.

  • But what we don’t know (and won’t until Hera arrives in 2026) is how effective the impact was.
  • Hera will investigate in detail – and its results will help to define Earth’s planetary defence protocol.

Europa Clipper

  • Launching almost at the same time as Hera is a Nasa flagship mission: the Europa Clipper to Jupiter’s icy moon, Europa.
  • Excitingly, Europa may host life in the form of a substantial fauna analogous to the animals that live on the deep ocean floor around hydrothermal vents.
  • Europa Clipper will fly past Europa between 40 and 50 times, taking detailed images of the surface, monitoring the satellite for icy plumes – and, most importantly, looking to see whether this moon has the conditions suitable to support life.
  • The investigation will be complemented by observations from Esa’s Juice mission, which is currently on its way to Jupiter.

MMX

  • I will finish it with my anticipation of further delights to come.
  • The launch of the Japanese Space Agency’s Martian Moon Exploration (MMX) mission to Phobos is currently scheduled for September 2024, and designed to return material to Earth in 2029.
