NASA telescope can capture 100,000 cosmic explosions

NASA’s upcoming Roman Space Telescope will change our understanding of the universe by detecting an estimated 100,000 cosmic explosions in a two-year survey.

Launched in 2027, the Space Observatory will scan the same sky every five days, creating a time-lapse movie of star death, black holes feeding crazy fanaticism, and possibly the first explosion stars in the universe, which dates back 11 billion years.

This display of cosmic fireworks will provide unprecedented insights to dark energy, a mysterious force that drives the accelerated expansion of the universe. Scientists predict that investigations will revolutionize multiple areas of astronomy while discovering phenomena that have never been observed.

Supernova Gold Rush

High-latitude time domain surveys represent the most ambitious cosmic explosion hunt ever. Benjamin Rose, an assistant professor at Baylor University, led the study published in the Journal of Astrophysics, highlighting the widespread impact of the investigation: “Do you want to explore dark energy, dying stars, the power of the galaxy, and maybe even something completely new we’ve never seen before, this investigation is all gold mines.”

Rome’s main target was the IA supernova – a stable explosion used as a cosmic measuring rod as they achieved consistent peak brightness. The telescope is expected to detect about 27,000 of these events, about ten times the sum of all previous surveys.

What makes this particularly exciting is that the Romans have a deeper understanding of the history of the universe than ever before. Although most previously detected Type IA supernova occurred within the past 8 billion years, the Romans will observe explosions that exploded thousands of years ago, with dozens of potentially returning to 11.5 billion years.

Explosion beyond the standard

The survey will capture a diverse universe of Menagerie beyond the main supernova targets:

  • Core outbreak supernova: About 60,000 explosions of fuel from large stars
  • Tide damage events: 40 examples of black holes shattering nearby
  • Super wet supernova: 90 explosions can exceed 100 typical supernova
  • Kilonovae: Five collisions between neutron stars or neutron stars and black holes
  • Paired Supernova: More than 10 explosions of the first superstars in the universe

Each type offers unique scientific opportunities. Kilonovae, for example, forged heavy elements such as gold and platinum in its consequences, but only one has been found so far. The discovery of Rome could divide this number into five.

Hunting the original giant

Perhaps most interesting is that the Romans might first confirm the detection of paired stable supernova – exploring from the first generation of stars in the universe. These primitive giants are hundreds of times larger than our sun, with little to no heavy element yet formed.

Their explosion was so powerful that nothing left behind, when the gamma rays were converted into matter-anti-focus pairs, it caused a catastrophic collapse and totally destroyed. Ross expressed confidence in these findings: “I think the Romans will first confirm the detection of paired hypernovas. They are very far away and very rare, so you need a telescope that can investigate a lot of the sky deep in the near-infrared light, which is the Romans.”

The universe history of dark energy

The huge supernova dataset will solve one of the biggest problems of cosmology: the nature of dark energy. By measuring how the rate of expansion of the universe changes over different cosmic eras, scientists can track the evolution of dark energy over time.

Current evidence suggests that dark energy itself has changed in the history of the universe, but the gap in our observational record makes this difficult to confirm. Rome’s ability to detect supernova at unprecedented distances will fill these critical gaps.

Ross points out a broader implication: “Filling these data gaps may also fill in the gap in our understanding of dark energy. There is evidence that dark energy has changed over time, and Rome will help us understand this change by understanding the changes in the universe’s history in which other telescopes cannot explore.”

Machine learning fits cosmic discovery

Distinguishing different types of explosions requires complex analytical techniques. Maryland – Rebekah Hounsell, an assistant research scientist at the University of Maryland-Baltimore County who works at NASA’s Goddard Space Flight Center, explains this approach: “By seeing the object change in a way that changes over time and breaking it into a spectrum – with individual colors – patterns of objects with light about the light, it can reveal information about flashes that emit all the different types of flashes.

The research team created a comprehensive dataset that will train machine learning algorithms to automatically classify Roman discoveries. Given the huge amount of data that the telescope will generate, this automation approach is crucial.

Hounsell acknowledged the wider impact of the investigation: “In search of type IA supernova, the Romans will collect a lot of “bysitting” of the universe – other phenomena that are not useful to some scientists, but are invaluable to others.”

Looking forward to an unexpected

Rome’s investigation may reveal a completely unknown type of cosmic phenomenon. The combination of telescope’s wide field of view, depth sensitivity and conventional surveillance creates ideal conditions for stumbled discovery.

Future iterations of the simulation may combine other cosmic variables such as active galaxies and excellent variability. Other telescopes may follow up on Rome’s most interesting findings, thus studying them in different wavelengths for in-depth understanding.

As Hounsell expected: “The Romans will find a bunch of weird and wonderful things in space, including some we haven’t even thought of yet. We will certainly expect something unexpected.”
