This discovery is significant as it suggests that complex organic molecules, the building blocks of life, were present in the early stages of our Solar System.<br /><br />Pyrene, a polycyclic aromatic hydrocarbon (PAH), is a relatively large and stable molecule. Its presence in interstellar space challenges the conventional belief that complex molecules cannot survive the harsh conditions of star formation. The detection of pyrene indicates that these molecules can endure and even thrive in the extreme environments of space.<br /><br />The discovery of pyrene is particularly exciting because it aligns with previous findings from the <keyword id="23694042" type="General" weightage="20" keywordseo="asteroid-Ryugu" source="keywords">asteroid Ryugu</keyword>, where significant amounts of pyrene were identified. This suggests that these molecules may have been inherited from the interstellar cloud that preceded our Solar System.<br /><br />While pyrene itself is difficult to detect directly, scientists utilise a tracer molecule called 1-cyanopyrene. By observing the radio emissions of 1-cyanopyrene, researchers were able to infer the presence of pyrene in the Taurus Molecular Cloud.<br /><br />The implications of this discovery are profound. It strengthens the hypothesis that complex organic molecules, essential for the emergence of life, were delivered to Earth through comets, asteroids, or interstellar dust. This cosmic infusion of organic matter may have provided the initial spark for the development of life on our planet.<br /><br />As scientists continue to explore the universe, we may uncover even more complex molecules and gain deeper insights into the origins of life. This latest discovery brings us one step closer to unravelling the mysteries of our cosmic origins and the potential for life elsewhere in the universe.<br />

The surrounding coarse grains, which are more resistant to heat, may have prevented water and the organic matter from being altered by the environment, the report said.<br />Hayabusa2 left Earth in 2014 and reached its stationary position above Ryugu in June 2018 after travelling 3.2 billion km on an elliptical orbit around the Sun for more than three years.<br />The probe touched down on the asteroid twice the following year, collecting the first-ever subsurface samples from an asteroid.<br />Researchers have previously found that Ryugu, born from a parent body formed in the outer solar system, travelled to the inner solar system and that its particles contain amino acids -- organic compounds said to be the "source of life."<br /><br /><strong>SEE ALSO:<br /><a href="https://www.businessinsider.in/sustainability/news/400-acre-barrens-in-trichy-district-i[%E2%80%A6]-to-turn-into-a-palm-tree-forest/articleshow/93588898.cms">400-acre barrens in Trichy district in Tamil Nadu to turn into a palm tree forest</a><br /></strong><a href="https://www.businessinsider.in/sustainability/news/human-activities-disrupted-even-the-m[%E2%80%A6]es-in-the-earths-ecosystem-study/articleshow/93590471.cms"><strong>Human activities disrupted even the most resilient species in the Earth's ecosystem: study</strong></a><br />

Launched in September 2022, DART, or the Double Asteroid Redirection Test, was a groundbreaking experiment. It intentionally collided a spacecraft with the small asteroid <keyword id="20759966" type="General" weightage="20" keywordseo="dimorphos" source="keywords">Dimorphos</keyword>, not to obliterate it, but to subtly alter its trajectory, showcasing our capability to avert potentially hazardous asteroids in the future.<br /><br />Recent research suggests that DART may have done more than just redirect Dimorphos; it might have significantly reshaped the asteroid's form. This revelation not only provides clues about Dimorphos' origin but also implies that the upcoming mission to study it will encounter a transformed asteroid rather than an impact crater.<br /><br />DART's endeavor left scientists uncertain about its long-term consequences and its implications for understanding Dimorphos. Planetary scientist Sabina Raducan and her team chose to simulate the effects of DART's impact rather than directly observing Dimorphos. They recreated Dimorphos and the DART impact, analyzing various outcomes like momentum transfer, ejected material, and Dimorphos' composition and density.<br /><br />Asteroids vary in composition; some are dense remnants of planetary formation, while others are loosely assembled conglomerates of dust and rock. Both <keyword id="20759967" type="General" weightage="20" keywordseo="didymos" source="keywords">Didymos</keyword> and Dimorphos fall into the latter category of "rubble piles." Surprisingly, simulations indicate that DART's impact did not create a crater but instead caused a widespread alteration of Dimorphos' surface, suggesting it is exceedingly weak and more akin to a "rubble pile" than previously believed.<br /><br />Its strength is estimated to be minimal, comparable to asteroids Ryugu and <keyword id="20186562" type="General" weightage="20" keywordseo="bennu" source="keywords">Bennu</keyword>, which have been studied by spacecraft. Additionally, simulations suggest that Dimorphos has a low density, denser than Ryugu and Bennu but still significantly less dense than Earth. This aligns with the hypothesis that Dimorphos formed from debris shed by Didymos due to its rotational motion.<br /><br />The European <keyword id="41531" type="General" weightage="20" keywordseo="space" source="Orion">Space</keyword> Agency's forthcoming Hera mission will play a critical role in validating these findings. If Hera's observations coincide with the simulations, it will offer valuable insights into Dimorphos' evolution, asteroid formation, binary systems, and future deflection techniques.<br /><br />This research not only sheds light on Dimorphos but also underscores the potential for similar asteroids to undergo substantial changes. Overall, it furnishes essential knowledge for future asteroid exploration and deflection endeavors, highlighting the unpredictability of space exploration, even when meticulously planned.<br />

One is dust from the surface of Asteroid Ryugu and the other is underneath the surface.<br /><br />The material from under the surface of Asteroid Ryugu is thought to be unchanged since the universe first came into existence. And, if scientists find organic material within these samples, it could provide answers to some of humanity’s burgeoning questions like how did life begin in the universe, even before it started on Earth?<br /><br />“We still don’t know the origin of life on Earth and through this Hayabusa-2 mission, if we are able to study and understand these organic martial from Ryugu, it could be that these organic materials were the source of life on Earth,“ Hayabusa-2’s mission manager, Makoto Yoshikawa, told the press shortly before the capsule <a href="https://phys.org/news/2020-12-japan-capsule-asteroid-samples-australia.html">landed in Australia</a>. <br /><br />According to him, JAXA only needs around 0.1 grams of dust to conduct all of its research.<br /><br /><strong>The journey isn't over for Hayabusa-2<br /></strong>The samples from Hayabusa-2 are back on Earth, but the probe is not done exploring the universe yet. After its visit to Asteroid Ryugu, the probe is now headed towards a smaller asteroid dubbed 1998 KY26. This journey is expected to take ten years to complete — one way. <br /><br />So, the next time we hopefully hear from Hayabusa-2 will be after two decades. <br /><br />The probe’s success with Ryugu, where it could touch down on the surface twice, indicates that getting to 1998 KY26 shouldn’t be a problem. Only one thing stands in its way — the possibility that Hayabusa-2 may run out of fuel.<br /><br />The return of Hayabusa-2’s samples comes within weeks of the National Aeronautics and Space Administration (NASA) OSIRIS-REx probe conducting its own successful heist from Asteroid Bennu. <br /><br /><strong>SEE ALSO:<br /><a href="https://www.businessinsider.in/india/news/petrol-is-less-than-a-rupee-away-from-being-more-expensive-than-it-has-ever-been-for-indian-consumers/articleshow/79601841.cms">Petrol is less than a rupee away from being more expensive than it has ever been for Indian consumers</a><br /><br /></strong><a href="https://www.businessinsider.in/finance/banks/news/icici-bank-is-capitalising-on-hdfc-banks-setback-with-its-own-digital-services-but-analysts-warn-that-market-share-isnt-all-that-matters/articleshow/79606479.cms"><strong>ICICI Bank is capitalising on HDFC Bank's setback with its own digital services but analysts warn that market share isn't all that matters</strong></a><br />

There’s now proof that half of the world’s oceans came from outer space

<p>Japan has landed two hopping robots onto asteroid Ryugu as part of the Hayabusa2 mission. It's Japan's second mission to an asteroid, where it plans to return some samples of Ryugu to Earth by the early 2020s. So that scientists can study the samples with more sophisticated instruments and hopefuly uncover some of the biggest scientific mysteries of all. Following is a transcript of the video.</p><p>On September 21, Japan's space agency made history. It became the first country to land not one, but two rovers onto an asteroid. Already, the unmanned rovers have sent back the first images while on the surface. And no, so far it's looking like there are no alien cities on its surface. But this mission, called Hayabusa2, could ultimately help solve one of the grandest scientific mysteries of all: Where did life on Earth come from?</p><p>Scientists have been studying asteroids for years. NASA, for example, landed its N.E.A.R Shoemaker spacecraft on asteroid Eros in 2001. But its Japan's space agency that is the first to deploy a pair of rovers to explore an asteroid's surface. Japan launched the Hayabusa2 mission in December, 2014. So, it has already been about 3.5 years in the making.</p><p>The spacecraft rendezvoused with its target in June 2018. Snapping a series of pictures that revealed the asteroid's shape. The asteroid of choice was 162173 Ryugu, or Ryugu for short. In Japanese it refers to a magical, underwater Dragon Palace. Now, the asteroid flies through space, around the sun ever 16 months. Conveniently between the orbits of Earth and Mars.</p><p>Making it an ideal target for the mission. Which, if all goes according to plan, will return a sample of the asteroid to Earth by the early 2020s. As the spacecraft flew closer to the asteroid's surface, it prepared to deploy its first two unmanned rovers. But these guys aren't your typical space rover. They're slightly bigger than the size of a large iPhone. Measuring just 7 by 18 centimeters. And they won't be driving around on the asteroid's surface. They'll be hopping.</p><p>Yup, you heard that right. Hopping. Japan designed the rovers with a spinning cylinder inside that gives it the power to hop about a few meters at a time. This reduces the risk of getting stuck on the rocky, uneven surface. But it doesn't come without it's own risk. Asteroids are relatively small and therefore have a weak gravitational pull. And even by asteroid standards, Ryugu is tiny. It's less than a kilometer across, making it no larger than a few city blocks. So, if the rovers hop too high, they could potentially go flying off into space. But so far, the mission looks good.</p><p>The rovers have already achieved their first hop. Now, this may be the first time Japan has landed on an asteroid but it won't be the last. These two rovers are just the first of four that Japan aims to land on Ryugu. The other two rovers are scheduled to land within the next year. In the process, Japan hopes to collect and return a sample of Ryugu to Earth. So that scientists can study it in more detail, looking for traces of water and organic material. If it turns out that asteroids like Ryugu contain similar material that we see on Earth it would be strong evidence for the idea that life on Earth first came from an asteroids billions of years ago. But this is a mystery that we can only answer if we study asteroids directly.</p>

Most of them hang out in the asteroid belt between Mars and Jupiter, though Ryugu's orbit sometimes takes it between Mars and Earth.</p><p>Some asteroids date back to the dawn of our solar system 4.5 billion years ago, when materials leftover from the formation of planets coalesced into these chunks of rock. In that sense, asteroids can serve as time capsules: What scientists find in those primitive rocks could tell us a lot about the solar system's history.</p><p>Ryugu is a C-type asteroid, which means it's rich with organic carbon molecules, water, and possibly amino acids. Amino acids form the building blocks for protein and were essential to the evolution of life on Earth. Some theories posit that an asteroid first brought amino acids here, gifting our planet with the seeds of life, though that's still debated.&#xa0;</p><p>About three-quarters of our solar system's asteroids are C-type.
