Mysterious Visitor in the Solar System
Scientists continue to study ‘Oumuamua, a mysterious object that came to the Solar System from outside. These distant extraplanetary objects have astounded humans with shape and science. Recent research continues that ‘Oumuamua is likely not a comet or asteroid, but a structure with a completely different structure. The Oumuamua asteroid, which entered the solar system in October, was observed with the Green Bank Telescope within the framework of the Breakthrough Listen program, financed by Russian billionaire Yuri Milner, a technology investor in Silicon Valley, California, USA. In the statement made on the website of Breakthrough Listen, it was stated that no extraterrestrial signal was found in the 400-meter-long celestial body moving at 87 kilometers per second during the examinations. It was revealed that the interstellar visitor ‘Oumuamua, discovered last year, may have come from a double star system. The ‘Oumuamua’, which the University of Hawaii discovered in October and resembles a cigarette with its much longer length than its width, is described as the first interstellar visitor to be observed from Earth. ‘Oumuamua’ means the first messenger to arrive from afar in Hawaiian. According to the British Guardian newspaper, scientists modeled ‘Oumuamua on a computer months after its discovery and concluded that rock-like objects like it came from a double star system rather than a single star system.
Artemis Program: Towards the Goal of Putting Humans on the Moon
NASA’s Artemis program is moving towards its goal of sending astronauts to the Moon by 2024. This exciting mission aims to Explore the resources in the Lunar assets and prepare for the deep space missions achieved. As part of Artemis, a lunar probe was landed to gather more information about water resources and potential settlements.
The team that will take part in the Artemis II mission to be realized within the framework of NASA’s Artemis Lunar Program, which aims to transport humans to the Moon, has been announced. The first thing NASA wants to do as part of the Artemis project is to land on the South Pole of the Moon.
NASA introduces astronaut team Before the crewed flight to be made in lunar orbit, NASA introduced the team that will take part in the Artemis II mission with the event held at the Johnson Space Center in Houston, Texas.
For the first time, a woman and a black astronaut took part in the crew on the lunar mission. NASA Director Bill Nelson said in a statement, “The Artemis II crew represents the thousands of people who have worked tirelessly to get us to the stars. This is humanity’s crew. We go.” said.
Euclid prepares to blast off on a mission to discover the fate of the Universe
The European Space Agency’s (ESA) Euclid space telescope will blast off from Cape Canaveral on 1 July on a mission to shed light on the ‘dark universe’ dominated by dark matter and dark energy.
Only 4.9 per cent of the universe is made from visible matter – i.e. the stuff that we can see and taste and touch and is made from atoms. This includes all the stars, gas, dust, planets, asteroids, comets and so on in the cosmos. The remainder is composed of dark matter (26.8 per cent) and dark energy (68.3 per cent). The fact that the nature of both, and hence the nature of the vast majority of the universe, remains mysterious is “the biggest embarrassment in cosmology”, ESA’s Guadalupe Cañas-Herrera told reporters during a pre-launch press conference on 23 June. “We know that 95 per cent of our universe is something that is totally unknown to us,” she added.
Dark energy, meanwhile, is some kind of repulsive energy field that permeates the universe and has an anti-gravity effect. Whereas gravity tries to slow the expansion of the universe, dark energy is working against gravity and over the past 10 billion years has caused the expansion of the universe to accelerate. “Euclid will observe the past 10 billion years, from when most of the stars and galaxies had formed and when dark energy started to be dominant,” said the mission’s Project Manager, ESA’s Giuseppe Racca.
Sun Releases Strong Solar Flare
The Sun emitted a strong solar flare on July 2, 2023. Solar flares are powerful bursts of energy that can impact various systems on Earth such as radio communications, electric power grids, navigation signals and spacecrafts. NASA’s Solar Dynamics Observatory captured an image of the solar flare. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in teal. This flare is classified as an X1.0 flare. X-class denotes the most intense flares, while the number provides more information about its strength.
Earthworm Robots Could Help Astronomers Explore Other Worlds
Earthworm robots inspired by nature could be used for exploring planets and moons in the solar system. Soft robotics, with flexible bodies made of silicone or rubber, allows for movements and navigation in confined spaces. Soft robots can stretch, twist, and burrow into soil, but they face challenges in the vacuum of space. Hard robotics, with rigid bodies made of plastics or metals, are better suited for extreme environments and carrying heavy loads. Earthworm robots mimic the peristaltic movement of real earthworms to propel themselves forward. The earthworm robot prototype has segments with bellows-type systems that elongate or compress, simulating the shape changes in an earthworm’s body. The ability to burrow is important for collecting soil samples and avoiding harsh surface conditions. The current model of the earthworm robot struggles with moving through coarse soil, but improvements are being explored for future space exploration missions.

The Astronomy Photo of the Year 2023 Award Awaits its Winner
The world’s largest astrophotography competition is completing its 15th anniversary. The Royal Observatory of Greenwich, which organizes the competition, has officially released nineteen photos from the competition, one of which will be announced as the overall winner at the awards ceremony on 14 September. Each year, the Royal Greenwich Observatory brings together a jury of art and astronomy experts for the competition. This year, over 4,000 applications were received from 64 different countries. We will be eagerly awaiting the results of this important competition, which offers a visual feast.
