Ghostly particles can give advance warning that a star is about to explode.

Trillions of particles from distant stars and galaxies are streaming through your body every second—you just can’t feel them. These ghost-like particles are called neutrinos. Although the universe spits them out constantly, these objects barely interact with matter—they can even slip through humanity’s toughest barriers, such as steel or lead walls.

Re: Planned Earthly or Space Telescopes - from any nation

This post is about a "telescope" for gamma rays that is quite different from the usual concept of a telescope.

https://www.msn.com/en-us/news/technolo … ddd&ei=116

A team of researchers in Japan performed an interesting balloon-borne experiment in 2018 during which they tried to record gamma-ray activity using a stack of photographic films and a star camera.

They recently published the results of their experiment and it turns out that their balloon-borne device is probably one of the most powerful gamma-ray telescopes, capturing gamma-ray activity at 40 times higher resolution than standard gamma-ray telescopes.

Using the same device, the researchers were also able to produce the sharpest and most accurate image of the Vela pulsar, a fast-spinning magnetized neutron star located 1000 light years away from Earth. 

Vela pulsar is so densely packed that if you take out one tablespoon of its matter, it will weigh the same as Mount Everest. The new telescope could help scientists study many objects like the Vela pulsar in detail.

However, the most fascinating thing about the balloon-borne device is that it takes its inspiration from pancakes.

Significance of gamma-rays

Everything visible to us in the universe is not everything the universe possesses. We can only see objects that emit light in the visible spectrum.

However, many celestial objects only emit light in the form of gamma rays, radio waves, X-rays, UV radiation, and more.

This is why scientists need special telescopes to capture these light rays and study celestial objects that would otherwise remain invisible to them.

Gamma rays have the highest energy among all electromagnetic radiations. They are emitted by the most powerful celestial objects such as pulsars, matter surrounding a black hole, and neutron stars,
They are also emitted during cosmic events characterized by high-energy releases. For example, supernova explosions, collisions between two celestial objects, and blazars (giant galactic nuclei with black holes at their centers).

All such objects and events play an important role in shaping our universe, and they can mainly be studied by observing their gamma-ray activity.

However, it’s highly challenging for astronomers to record gamma rays because they have incredibly short wavelengths as compared to any other electromagnetic waves.

“They don't interact with matter in the same way as other forms of light and thus can't be deflected with lenses or detected by standard sensors,” the researchers noted.

“Thus, there is a gap in our ability to detect the light coming from fascinating stellar objects such as supernovae and their remnants.”

Detecting gamma-rays using new telescope

Before digital cameras became a reality, photographs were captured using cameras that used emulsion films.

In fact, photographic emulsion films were the first material that scientists employed to detect radioactivity. These films have high sensitivity and are also great at tracing gamma-rays, according to the study's authors.

This is why they used the film material in their telescope design. However, instead of using a single film, they stacked multiple photographic films together.

“The idea was to stack up a few of them to accurately capture the trajectory of the particles that the gamma-ray produces on impact, just like a single pancake may capture where you poke a straw into it, but it takes a whole stack to record the straw's direction” the researchers explained.

They installed this setup on an observation balloon along with a set of star cameras (special cameras used to observe constellations and star patterns) and a device that caused back-and-forth movement of the stacked films at different speeds.

The balloon was allowed to go up to 40 km in height. However, at such distances, winds disturbed the orientation of the balloon.

The cameras solved this issue by recording the change in the direction of the setup concerning the movement of starts at any point in time.

Meanwhile, scientists were able to accurately time gamma-ray activity and match it with camera footage by comparing the displacement of moving films.

Using the telescope, they captured an image of the Vela pulsar and traced several other gamma-ray events.

“We captured a total of several trillion tracks with an accuracy of 1/10,000 millimeters. By adding time information and combining it with attitude monitoring information, we were able to determine ‘when’ and ‘where’ the events originated with such precision that the resulting resolution was more than 40 times higher than that of conventional gamma-ray telescopes," said Aoki Shigeki, one of the study authors and a professor at Japan’s Kobe University.

Device opens new possibilities

The utility of the proposed telescope goes beyond capturing gamma rays. The study authors suggest that it might enable them to trace many other waves in the electromagnetic spectrum that have never been recorded before.

Moreover, the pancake-inspired device may also help them capture more details within the gamma-ray frequency band.

Using the new telescope, “We can attempt to contribute to many areas of astrophysics, and in particular to open up gamma-ray telescopy to 'multi-messenger astronomy' where simultaneous measurements of the same event captured through different techniques are required,” the researchers emphasized. 

However, whether the telescope will fulfill all these expectations is yet to be tested.

The study is published in The Astrophysical Journal.

At the APAC meeting, both Fox and Clampin said they were committed not just to keeping Chandra and Hubble going at reduced spending levels but also to the senior review process that astronomers worry is being short-circuited by the upcoming review.

“We are trying to find cheaper ways to operate Chandra and Hubble so that they are consistent with the budget allocation that we have,” Clampin said. “The decision was done this way because of the very significant impact to the budget that had to be dealt with on a short time scale. We didn’t have time to wait two years,” when the next regular senior review is scheduled.

NASA Planning a Spacewalk to Fix an older Busted X-ray Telescope


Astronauts To Patch Up NASA’s NICER Telescope
https://science.nasa.gov/missions/stati … telescope/
NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts.

In May 2023, scientists discovered that NICER had developed a “light leak.” Unwanted sunlight was entering the instrument and reaching the telescope’s sensitive detectors. While the team took immediate steps to mitigate the impact on observations, they also began thinking about a potential repair.

“The sunlight interferes with NICER’s ability to collect viable X-ray measurements during the station’s daytime,” said Zaven Arzoumanian, NICER’s science lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Nighttime observations are unaffected, and the telescope continues to produce incredible science. Hundreds of published papers have used NICER since the mission began. Blocking some of the light leaking in would allow us to return to more normal operations around the clock.”

China's 'lobster eye' Einstein telescope releases 1st batch of trippy space images
https://www.livescience.com/space/space … ace-images
Flaring stars, black hole outbursts and gamma-rays are just some of the cosmic exotica that Einstein Probe will hunt

The problem with X-rays is that they are so high in energy that they are difficult to capture with a standard detector. Lenses don't work because X-rays are too powerful to be easily refracted, and an X-ray striking a mirror face-on will simply pass through said mirror. Rather, X-ray detection is only possible when these rays strike a reflective surface at a shallow angle. From there, the rays can be directed towards an X-ray-specific detector. However, this mechanism poses a bit of a problem. It means an X-ray telescope can usually only detect X-rays along a narrow field of view; outside of that field of view, X-rays would strike at too great an angle.

As it turns out, lobsters are the solution — lobster vision, that is. What's more, scientists cottoned onto this basic idea back in the late 1970s, but it has taken decades to successfully adapt that idea for use on X-ray telescopes in space.

Einstein Probe is a collaboration between not only the Chinese Academy of Sciences and the European Space Agency, but also the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany and the National Centre for Space Studies (CNES) in France. Its discoveries will provide a huge catalog of objects for Europe's forthcoming NewAthena (Advanced Telescope for High-Energy Astrophysics) mission, which is currently in the study phase. Planned to be the most powerful X-ray telescope ever built, that instrument is set to launch around 2037.
