Planet-eating Stars More Common Than Previously Thought, Astrophysicists Find | Australia News | The ...

Planet-eating stars are more abundant in the universe than previously thought, an Australian-led study has found.

The study, by the Australian Research Council's Centre of Excellence for All Sky Astrophysics in Three Dimensions (Astro 3D), looked at "co-natal" or twin stars, born from the same molecular cloud, where one had "eaten" a planet and the other had not.

The researchers found one in 12 pairs of stars have absorbed entire planets or planetary material, changing their chemical make up.

Astronomers assumed such an event was possible, but the first planet-eating star was only caught in the act last year, and the latest study shows the cosmic consumption is more common than previously thought and can happen with younger stars.

NASA Is Recruiting A New Class Of Astronauts

"Typically, it's a very popular application," April Jordan, NASA's astronaut selection manager, said.

The odds that you will be chosen are slim. The last time NASA put out a call for applications, in 2020, more than 12,000 people applied.

It took the agency a year and a half to go through the applications. NASA selected just 10 of the hopefuls, or 0.083 percent. That makes Harvard's 3.5 percent acceptance rate among high school applicants appear bountiful.

Ms. Jordan is on a media tour to spread the word that " the right stuff " for being an astronaut in 2024 is not the same as what it was in the 1960s, when astronauts were all white men, almost all from the military.

NASA's DART Mission Hammered Its Target Asteroid Into A New Shape. Here's How

Now, however, scientists have shown that it seems DART didn't just give Dimorphos a push; it also hit Dimorphos with enough kinetic energy to reshape it.

Originally, Dimorphos would have been an oblate spheroid, which is kind of like a squashed ball. The impact of DART at 5 kilometers per second (3 miles per second) sent shockwaves through the asteroid, resulting in it becoming more elongated and shifting its axis of rotation off-center. The new shape is inferred by astronomers from the light curve of the Didymos–Dimorphos system, which is aligned in such a way that we can see them transiting and eclipsing one another.

Astronomers Confirm A New 'Trojan' Asteroid That Shares An Orbit With Mars

This article has been reviewed according to Science X's editorial process and policies . Editors have highlighted the following attributes while ensuring the content's credibility:

Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey round the sun, ahead of Mars and in the same orbit.

With this new member, the group of Trojans that accompany Mars has increased in number to 17. But it shows differences in its orbit and chemical composition which may indicate that it is a captured asteroid, of a primitive type. The results are published in Astronomy & Astrophysics .

The Future Of The Space Force Isn’t On Earth — It’s In The Solar System

At the ripe age of five, it is clear that the United States Space Force, while dominated by old thinking, still doesn’t know what it wants to be when it grows up, and is split among multiple different areas of focus. The challenge is that it has to grow up fast.

It seems the Force’s leadership are of three minds: those who look down, focusing on ground operations, those who look around at orbital space and those who look up and out.

Those who believe the Space Force should focus on what is happening on the ground refer to its support function for the joint force of all the current branches of the military. This ranges from communications, creating and protecting space-based command and control systems, observation and, in its most visionary (and ominous) form, operation of space-to-ground weapons.

The James Webb Space Telescope Is Digging Deep Into The Mysteries Of Gas Planets

Just last week, one team announced it may have some updates on the dynamics of gas giant formation, thanks to the JWST. More specifically, the researchers say they've started making headway in answering the question of how long gas giants likely have to form around their host stars before all the gas around those stars fades away.

The team used the JWST to probe what's (a little confusingly) known as the "disk wind." This doesn't really refer to a wind like you may imagine. Rather, it refers to the process of gas leaving a disk around a star. This "disk" would be one filled with different types of material with the potential to give rise to planets. It's thus otherwise known as a "protoplanetary disk."

Blue Origin Founders Want To Harvest Helium-3 From The Moon

Over billions of years, the surface of the Moon has been bombarded by solar wind, carrying high-energy particles that include a highly coveted resource, helium-3. Although the element is scarce on Earth, it has recently become in demand by several industries, including those working on quantum computing and nuclear fusion reactors.

"There is growing demand for Helium-3 across burgeoning and potentially massive industries," Alexis Ohanian, one of the main investors in Interlune's latest round of funding, said in a statement. "We invested in Interlune because access to the ample cache of Helium-3 and other precious natural resources on the Moon and beyond will unlock or accelerate technological advancements currently hindered by lack of supply."

Terran Orbital Announces Plans To Produce Small Satellites For Geostationary Orbit

WASHINGTON — Satellite manufacturer Terran Orbital announced plans to produce a new line of small satellite buses designed to operate in geostationary Earth orbit.

The company said it will compete in the so-called small GEO satellite market with a new bus named SmallSat GEO for satellites above 500 kg.

Small GEO satellites are an emerging class of spacecraft designed for geostationary orbit 22,236 miles above Earth’s surface. This orbital perch has traditionally been the territory of large, heavyweight communications satellites that beam data to permanently pointed antennas on the ground.
