In Upper Egypt, the so-called "red mercury" fever has emerged again. People obsessed with this substance have been looking for it in bats' nests, looking to make a fortune.

The red substance is estimated to be worth millions of Egyptian pounds in the markets of archaeological treasures seekers. 

Some have associated the red mercury with bats because their nests are located in the columns and ceilings of ancient Egyptian temples in Luxor and Aswan. 

Many wealthy people, especially in the Arab world, believe that red mercury can extend a person’s life and preserve youth.

Red mercury was rumored to be found in an ancient coffin found in the suburb of Sidi Gaber, Alexandria in July. 

At the time, Dr. Mostafa Waziri, secretary-general of the Supreme Council of Antiquities, refuted the rumors, saying the liquid found inside the coffin was "not the juice of immortality that belongs to mummies," or the so-called red mercury, but rather sewage water.

Sewage had seeped into the coffin through a small leak from the local sewage network.

Archaeologist Mohamed Yehia Oweida told the German news agency that red mercury is "just a myth" and it was never used in ancient Egypt.

The so-called Egyptian or Pharaonic red mercury does not exist, he stressed.

Moreover, until this date, there is no archaeological or scientific evidence that proves that ancient Egyptians used it in mummification.

He denied the rumored discovery of the ancient Egyptians’ so-called "immortality code", which has been sought by humans for centuries.

Oweida highlighted many popular fake myths related to red mercury, such as the discovery of a bottle containing red liquid at the Museum of Mummification in Luxor.

People obsessed with the liquid say the bottle contains red mercury, which can turn cheap metals into precious ones.

He explained that the bottle contained brownish-red liquid. It was found under the mummy of Amun Tefnakht, commander of Egyptian armies who lived during the 27th Dynasty.

The liquid was in fact a residue of some of the materials used in the mummification process, such as sawdust, and resin, aromatic fats and linen rolls.

The Sculptor galaxy is similar in many respects to our Milky Way. It is about the same size and mass, with a similar spiral structure. But while it is impossible to get a full view of the Milky Way from the vantage point of Earth because we are inside the galaxy, Sculptor is perfectly positioned for a good look.

Astronomers have done just that, releasing an ultra-detailed image of the Sculptor galaxy on Wednesday obtained with 50 hours of observations using one of the world's biggest telescopes, the European Southern Observatory's Chile-based Very Large Telescope.

The image shows Sculptor, also called NGC 253, in around 4,000 different colors, each corresponding to a specific wavelength in the optical spectrum.

Because various galactic components emit light differently across the spectrum, the observations are providing information at unprecedented detail on the inner workings of an entire galaxy, from star formation to the motion of interstellar gas on large scales. Conventional images in astronomy offer only a handful of colors, providing less information.

The researchers used the telescope's Multi Unit Spectroscopic Explorer, or MUSE, instrument.

"NGC 253 is close enough that we can observe it in remarkable detail with MUSE, yet far enough that we can still see the entire galaxy in a single field of view," said astronomer Enrico Congiu, a fellow at the European Southern Observatory in Santiago, and lead author of research being published in the journal Astronomy & Astrophysics.

"In the Milky Way, we can achieve extremely high resolution, but we lack a global view since we're inside it. For more distant galaxies, we can get a global view, but not the fine detail. That's why NGC 253 is such a perfect target: it acts as a bridge between the ultra-detailed studies of the Milky Way and the large-scale studies of more distant galaxies. It gives us a rare opportunity to connect the small-scale physics with the big-picture view," Congiu said.

Sculptor is about 11 million light-years from Earth, making it one of the closest big galaxies to the Milky Way. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

Like the Milky Way, it is a barred spiral galaxy, meaning it has an elongated structure extending from its nucleus, with spiral arms extending from the ends of the bar. Its diameter of about 88,000 light-years is similar to the Milky Way's, as is its total mass. One major difference is Sculptor's rate of new star formation, estimated to be two to three times greater than that of the Milky Way.

Nearly 30% of this star formation is happening near the galaxy's nucleus in what is called a starburst region, as revealed in colorful emissions shown in the new image.

The observations have given information on a wide range of properties such as the motion, age and chemical composition of stars and the movement of interstellar gas, an important component of any galaxy.

"Since the light from stars is typically bluer if the stars are young or redder if the stars are old, having thousands of colors lets us learn a lot about what stars and populations of stars exist in the galaxy," said astronomer Kathryn Kreckel of Heidelberg University in Germany, a study co-author.

"Similarly for the gas, it glows in specific bright emission lines at very specific colors, and tells us about the different elements that exist in the gas, and what is causing it to glow," Kreckel said.

The initial research being published from the observations involves planetary nebulae, which are luminous clouds of gas and dust expelled by certain dying stars. Despite their name, they have nothing to do with planets. These nebulae can help astronomers measure the precise distances of faraway galaxies.

The researchers marveled at the scientific and aesthetic value of the new view of Sculptor.

"I personally find these images amazing," Congiu said. "What amazes me the most is that every time I look at them, I notice something new - another nebula, a splash of unexpected color or some subtle structure that hints at the incredible physics behind it all."
