‘Spooky glow’ in the solar system may be a ‘new addition’ to our understanding of its structure – but its source remains a mystery

  • NASA’s Hubble telescope has detected a glow around the solar system
  • Scientists are mystified by this glow equivalent to 10 fireflies
  • The team theorizes it could be dust from comets falling into the solar system

A mysterious ‘ghostly glow’ has been found around us, equivalent to 10 fireflies solar system that persists even when other light sources such as stars and planets are subtracted.

The discovery was made when astronomers set out to see just how dark space can be, which they did by sifting through 200,000 images sent by NASA‘s Hubble Space Telescope and eliminating the expected glow – but a little excess of light prevailed.

Scientists can’t be sure where the light is coming from, but guess the source is a previously unknown sphere made of dust from comets, which reflects sunlight.

If confirmed, researchers said this dust envelope would be a new addition to the solar system’s known architecture.

This discovery builds on research conducted in 2021 when another group of astronomers used data from NASA’s New Horizon interplanetary space probe to measure the sky background.

New Horizon also detected a glow around the solar system, but the probe was more than four billion miles from the sun, and what caused it remains a mystery to this day.

Numerous theories range from the decay of dark matter to a vast unseen population of remote galaxies.

Tim Carleton of Arizona State University (ASU) said in a pronunciation: ‘If our analysis is correct, there is still a dust component between us and the distance where New Horizons measured.

The team was measuring the darkness of the sky, subtracting the zodiacal light, the glow given off by stars, planets

“That means this is some kind of extra light coming from inside our solar system.”

Carleton went on to explain that since the light appeared dim in the New Horizons data due to its distance, the glow must be coming from within the confines of the solar system.

“It may be a new element in the content of the solar system that has been hypothesized but has not been quantitatively measured so far,” he said.

This led to the recent work to use Hubble, which is about 340 miles above the Earth’s surface.

Veteran Hubble astronomer Rogier Windhorst, also of ASU, said in a statement: “More than 95 percent of the photons in the Hubble archive images come from distances less than 3 billion miles from Earth.

Since the very beginning of Hubble, most Hubble users have discarded these aerial photons because they are interested in the fuzzy discrete objects in Hubble’s images, such as stars and galaxies.

“But these aerial photons contain important information that can be extracted thanks to Hubble’s unique ability to measure faint brightness levels with high precision over its three decades of life.”

Hubble, a joint project of NASA, the European Space Agency and the Canadian Space Agency, has been observing the universe for more than three decades.

It has made more than 1.5 million observations of the universe and more than 18,000 scientific papers have been published based on its data.

The telescope orbits the Earth at a speed of about 27,000 km/h in a low Earth orbit at an altitude of about 340 miles, slightly higher than the International Space Station.

Launched in April 1990 from the Kennedy Space Center in Florida, Hubble is showing increasing signs of aging, despite a series of repairs and updates by spacewalking astronauts during the NASA shuttle era.

The telescope is named after the famous astronomer Edwin Hubble who was born in Missouri in 1889 and discovered that the universe is expanding and the rate at which it is expanding.
