Webb Telescope Snaps Some Of Its Largest Images, And They’re Majestic

Published

on


Ancient Mayan culture referred to the Orion Nebula as the cosmic fire of creation.

Contemporary scientists see that enormous cloud of gas and dust in space in a somewhat similar way. The vast baby star nursery, south of Orion’s belt, is about 1,350 light-years away, making it the closest large star-forming region to Earth. Because of its proximity, it’s a prime target for astronomers to study the births of stellar objects.

Within the nebula, aka Messier 42, are protostars (precursors to stars), brown dwarfs (failed stars too small to generate their own nuclear power), and rogue planets (worlds that wander through space unhitched to a host star).

Now with the James Webb Space Telescope, scientists are able to see this important celestial site with unparalleled resolution. The telescope, a partnership of NASA and the Canadian and European space agencies, reveals the cosmos in infrared, a form of light that isn’t visible to human eyes. The data, translated into colors people can see, offer a plethora of new insight.

Researchers have released new wide-angle views of the Orion Nebula that could enrich our understanding of star evolution. Two images are some of the largest mosaics from Webb so far. The new Webb data have uncovered hundreds of free-floating worlds in the nebula, not orbiting stars, the smallest of which are two times the mass of Saturn, according to ESA.

A European Space Agency tool known as ESA Sky allows users to zoom in and explore the details. Some 2,400 individual images were combined to make the full short-wavelength color composite view, and 712 individual images were combined to obtain the long-wavelength one, according to ESA.

In this short wavelength mosaic image, Webb focuses on the nebula and its stars.

In this long wavelength composite image, Webb focuses on the gas, dust, and molecules in the region.

At the center of the nebula are four massive stars collectively known as the Trapezium because they are arranged in a trapezoidal shape.

Webb astronomers looking at the Orion Nebula recently detected a curious carbon molecule in a young star system, known as d203-506. Organic chemists say the molecule, methyl cation, assists with the formation of more complex carbon-based molecules, acting like a train station where a molecule can remain for a time before routing to one of many different directions to react with other molecules.

The discovery was published in the journal Nature in June.

Earth To Get A Second Moon Soon; Here’s What You Must Know

Published

By



Earth is about to get a new moon, at least for a while. This moon will actually be the asteroid 2024 PT5 discovered on August 7, 2024. It is around 10 meters (33 feet) in diameter and will be captured by Earth’s gravity from September 29 to November 25.

The asteroid will circle around Earth during this period but won’t complete a full orbit. After November 25, it will break free from Earth’s gravitational pull and continue orbiting the Sun.

In a paper published in Research Notes of the American Astronomical Society, researchers explained how certain near-Earth objects (NEOs) can briefly become mini-moons. These objects, like 2024 PT5, approach Earth at a slow speed and are close enough for our planet’s gravity to temporarily capture them. However, they don’t stay long enough to make a full revolution around Earth.

Asteroid 2024 PT5 is a near-Earth object and belongs to the group that have orbits similar to Earth’s. Since its speed is low and is close to our planet, its trajectory easily gets influenced by bodies with heavier mass.

During its brief visit, 2024 PT5 will offer scientists a unique opportunity to study how Earth’s gravity affects the paths of near-Earth objects. By understanding this interaction, astronomers can improve their predictions for finding asteroids that might be heading for a direct collision with our planet.

Researchers pointed out that this isn’t the first time Earth has captured a temporary moon. Another asteroid was temporarily captured by Earth between 1981 and 2022 during a flyby.

Mini-moons like 2024 PT5 are also of interest to those working in asteroid mining and space exploration. Because they are relatively close to Earth and accessible, they could be valuable targets for future missions aiming to study or even extract resources from asteroids.

Will Asteroid Apophis Strike Earth? New Study Flags Possibility Of Disaster In 2029

Published

By



NASA has assured that there is no threat from asteroid Apophis which is set to fly past our planet in 2029. But a new study has come forth suggesting there is now a very slight chance it might collide with Earth.

Paul Wiegert, an astronomer at Canada’s Western University, has published a study in The Planetary Science Journal warning about a potential collision. He claims that there is a chance less than one in two billion that the 375-metres-wide Apophis may end up striking our planet, Futurism reported.

He took into account the collision of Apophis with smaller space rocks while on its way to Earth. The collisions, according to Weigert, may tweak Apophis’s trajectory sending it hurtling toward us. Apparently, other astronomers including those at NASA did not consider this possibility.

The scientist estimated that an asteroid just 11 feet wide could nudge it toward Earth for a collision in 2029 and smaller ones (about two feet wide) could cause a collision in 2036 or 2068.

But none of it is absolutely confirmed as Weigert says we’ll have to wait until 2027 to be absolutely sure. The expert underscored that it will be tricky to know if Apophis was struck by a smaller rock as the after-effects might soon dissipate.

Apophis, named after the Egyptian god of chaos and destruction, will be at its closest on April 13, 2029. Estimates suggest it will pass from a distance of about 32,000 kilometres and the European Space Agency (ESA) has announced Ramses mission to study it up close. NASA and ISRO are also planning to use this opportunity of studying the asteroid in order to ultimately strengthen planetary defense.
