By National Geographic Staff WriterIn the sky is a constellation called the Southern Cross.

Its brightest star is a yellow-white and is about 30 light years away.

Its second brightest star, the white dwarf, is about 20 light years from Earth and is a bit more than half the mass of the sun.

This makes the Southern Star the brightest star in the sky, according to new research.

The Southern Cross was discovered in 1964 and named after French astronomer and astronomer Charles Messier.

Messier is widely credited with discovering the Southern Hemisphere’s best-known star, a blue giant, which is located just a few hundred light years off the equator.

Messier found that the Southern star was more similar to the Northern Star, a star with a yellowish glow.

Messiers research led to the name Southern Cross, which he called a new name for the star.

The name is a reference to Messier’s famous observation that the northern hemisphere is actually located at the southern pole, according the Star Atlas website.

The two stars are both relatively nearby, but the Southern is much closer.

Messers research found that their distances are roughly the same, meaning they are close enough to be seen from Earth.

“They’re so close, it’s hard to miss,” said Neil Brown, a astronomer at the University of Texas at Austin.

“There’s no way to know if it’s a very faint object or a very bright object.”

Messier’s star is called the Sun, and it is a faint red-orange star.

Its color and brightness vary depending on the angle of the Sun’s rays from Earth’s sun, according Star Atlas.

“It is not bright enough to cause the Southern Stars to glow, but its brightness is sufficient to cause it to be visible to the naked eye from a distance of approximately 2,000 miles (3,200 kilometers),” the website said.

The star is located about 60 light years south of the southern star, in the constellation Cygnus.

It is the brightest object in the southern constellation, according National Geographic.

Messiers star is visible to people on the ground but can only be seen with a telescope.

That is because the Southern cross is a blue star, so it cannot be seen directly in a telescope because of its glare.

The new study, which was published online Thursday in the journal Nature Astronomy, is based on observations made by NASA’s Very Large Telescope.

The telescope has an array of telescopes in Chile that are designed to make the Southern object visible to us.

It also has a telescope in Hawaii, but no other observations of the Southern are available there.

Messers team analyzed more than 10 years of data collected by the telescope and found that its data were consistent with the Southern’s brightness.

Messiest research team also found that some of the data did not match the Southern as well as other astronomers had predicted.

For instance, the Southern was brighter in 2015, but it was not brighter in 2018.

Messiness also pointed out that there were some irregularities in the Southern stars data, including an odd pattern in the data that looked like the Southern had shifted around.

But he says the pattern did not seem to be due to changes in the telescope’s instrument or the alignment of the telescope.

Messieders team says it is now studying the Southern with the telescope in the hope that it can be more accurately used to make more accurate measurements.
