Ancient Egyptian temples followed astronomy to set their calendars

London, September 9 (ANI): A new study has indicated that ancient Egyptian temples were aligned so precisely with astronomical events that people could set their political, economic and religious calendars by them.

According to a report in New Scientist, the study was of 650 temples, some dating back to 3000 BC.

For example, New Year coincided with the moment that the winter-solstice sun hit the central sanctuary of the Karnak temple in present-day Luxor, according to archaeological astronomer Juan Belmonte of the Canaries Astrophysical Institute in Tenerife, Spain.

Hieroglyphs on temple walls have hinted at the use of astronomy in temple architecture, including depictions of the “stretching of the cord” ceremony in which the pharaoh marked out the alignment for the temple with string.

But there had been little evidence to support the drawings.

Belmonte and Mosalam Shaltout of the Helwan Observatory in Cairo found that the temples are all aligned according to an astronomically significant event, such as a solstice or equinox, or the rising of Sirius, the brightest star in the sky.

“Somebody would have had to go to the prospective site during a solar, stellar or lunar event – as we did – to mark out the position that the temple axis should take,” Belmonte said.

“For the most important temples, this may well have been the pharaoh, as the temple drawings show,” he added. (ANI)

Astronomers obtain first detection of magnetic field on bright star Vega

Paris, June 24 (ANI): Astronomers, using the NARVAL spectropolarimeter of the Bernard-Lyot telescope in France, have obtained the first detection of a magnetic field on the bright star Vega.

According to an article in the journal Astronomy and Astrophysics, astronomers clearly observe the magnetically-induced effect in the spectrum of Vega, thereby showing that the star possesses a magnetic field, something unknown so far.

Using the high-sensitivity NARVAL spectropolarimeter installed at the Bernard-Lyot telescope at the Pic du Midi Observatory in France, a team of astronomers detected the effect of a magnetic field (known as the Zeeman effect) in the light emitted by Vega.

Vega is a famous star among amateur and professional astronomers. Located at only 25 light years from Earth in the Lyra constellation, it is the fifth brightest star in the sky. It has been used as a reference star for brightness comparisons.

Vega is twice as massive as the Sun and has only one-tenth its age.

Because it is both bright and nearby, Vega has been often studied but it is still revealing new aspects when it is observed with more powerful instruments.

Vega rotates in less than a day, while the Sun’s rotation period is 27 days.

The intense centrifugal force induced by this rapid rotation flattens its poles and generates temperature variations of more than 1000 degrees Celsius between the polar (warmer) and the equatorial regions of its surface.

Astronomers analyzed the polarization of light emitted by Vega and detected a weak magnetic field at its surface.

This is really not a big surprise because one knows that the charged particle motions inside stars can generate magnetic fields, and this is how solar and terrestrial magnetic fields are produced.

However, for more massive stars than the Sun, such as Vega, theoretical models cannot predict the intensity and the structure of the magnetic field, so that astronomers had no clue to the strength of the signal they were looking for.

After many unsuccessful attempts in past decades, both the high sensitivity of NARVAL and the full dedication of an observing campaign to Vega have made this first detection possible.

he strength of Vega magnetic field is about 50 micro-tesla, which is close to that of the mean field on Earth and on the Sun.

This first observational constraint opens the way to in-depth theoretical studies about the origin of magnetic fields in massive stars.

Astronomers believe that this discovery will be a key step in understanding stellar magnetic fields and their influence on stellar evolution. (ANI)

Goody’s sons send ‘miss you’ messages to mum in bottle

London, April 5 (ANI): Jade Goody’s beloved sons have paid tribute to their late mum in their own special way, by tucking in ‘miss you’ messages in a bottle and launching it into the ocean from Australia.

The Brit reality TV star’s five-year-old Bobby and four-year-old Freddie, on vacation with dad Jeff Brazier, marked their mum’s funeral on April 4 by writing messages and drawing her pictures.

The lads were said to have had a private ceremony of their own with their father on the beach at a private resort near Sydney.

They further sent a funeral bouquet to their mummy, who wanted them to remember her as the “brightest star in the sky”, along with a touching request.

“Please speak to God and ask him to make the clouds go away on holiday because we can’t see the stars,” News of the World quoted them as saying.

“We love you very much and speak about you every day, we know you are with us when we play on the beach, eat our dinner and even when we are colouring in pictures for you, we know we can talk to you and you’ll hear us.

“You are always in our thoughts and in our hearts mum, we are proud of you and you’ll never to be forgotten,

“We miss you, love your little men, Bobby and Freddie,” they added.

While one message said: “To God, please give to our Mum”, another one read: “We love you Mummy and we miss you Mummy.”

It was alleged that by making the boys hop the funeral, Jeff was following Jade’s wish that she did not want her boys to have the last memory of their mother in a “box surrounded by people crying”. (ANI)
