Hubble Space Telescope Observes Conjunction of Two Spiral Galaxies

While it looks like a spiral galaxy called NGC 105 is plunging edge-on into a collision with a neighboring spiral galaxy, this is just the result of the chance alignment of the two objects in the sky.
NGC 105 is located approximately 215.5 million light-years away in the constellation of Pisces.
Otherwise known as IRAS 00226+1236, LEDA 1583 and UGC 241, this spiral galaxy has a diameter of 83,700 light-years.
NGC 105 was discovered by the French astronomer Édouard Stephan in October 1884.

Quadrantid Meteor Shower

The Quadrantid meteor shower occurs in January every year. The radiant of the shower lies in the Bootes constellation.
The meteor showers are caused due to debris or trail of dust left by a comet. When the earth moves through the left-over dust particles, they catch fire. How do they fire up? Earth revolves around the sun at a speed of 1,00,000 km/sec! When the dust particles encounter such huge speeds, large amounts of frictional forces are generated. These frictional forces produce the heat energy and fire the particles. Just like a match stick! Match stick is the earth and match box is the particle (not considering the weight).

China Launches 5-year Plan to Become a Hub of World Robotics Innovation

China announced a five-year roadmap to achieve its goal of becoming a global robotics innovation hub by the year 2025. China's Ministry of Industry and Information Technology revealed operating income from the country's robotics industry is expected to grow by around 20% per year between 2021 and 2025. From 2016 to 2020, the sector expanded at an average growth rate of 15%. Last year, operating income surpassed 100 billion yuan ($15.69 billion) for the first time.
To achieve its goal by 2025 of becoming a worldwide robotics innovation centre, China has proposed a strategy concentrating on improvements to essential components such as servo motors and control panels. As per the 2021 World Robot Report, South Korea, Singapore, and Japan were the top three most automated countries in Asia-Pacific.

South Korea to Develop Technology for Artificial Sun 'KSTAR' by 2026

The Korean government is planning to develop a technology for Korea's first artificial sun 'KSTAR' to maintain 100 million degrees for 300 seconds by 2026. The 300 seconds is the minimum time required for the commercialization of nuclear fusion technology.
The Ministry of Science and ICT announced on the 30th that it held the 16th National Fusion Committee at the Korea Institute of Fusion Energy and finalize the '4th basic plan of nuclear fusion energy development (2022-2026)'. The science ministry sets goals and directions of its policies for nuclear fusion energy development every 5 years.

First Magnetic Field on an Exoplanet

A team of astronomers used data from the Hubble Space Telescope for discovering the signature of a magnetic field on an Exoplanet. Such a feature has been seen on an exoplanet, for the first time.
A magnetic field around the planet explains the observations of an extended region of charged carbon particles. It streams away from it in a long tail.
Magnetic fields play a significant role in protecting planetary atmospheres.
Thus, the ability to detect the magnetic fields of exoplanets is a significant step of understanding what aliens' worlds may look like, in a better manner.
Researchers used the Hubble for observing the exoplanet HAT-P-11b. it is a Neptune-sized planet, located at a distance of 123 light-years from Earth.
Observations were made in ultraviolet light spectrum.

Iran Launches Satellite Carrier Rocket into Space

Iran launched a satellite carrier rocket bearing three devices into space, though it's unclear whether any of the objects entered orbit around the Earth.
Iran's semiofficial news agencies, did not say when the launch was conducted nor what devices the carrier brought with it. However, the launch comes amid difficult negotiations in Vienna over Iran's tattered nuclear deal.
Previous launches have drawn rebukes from the United States. The US State Department, Space Force and the Pentagon did not immediately respond to requests for comment.
