Earth's habitability is influenced by its orbital parameters—including the length of day, tilt of the axis, and orbital shape—which create stable seasons, sunlight, and temperatures suitable for land-based life.
NASA-funded researchers ran 93 simulations to understand how these parameters affect the potential for life on Earth-like planets.
A planet's day length matters: Days longer than 20 Earth days can lead to cooler land temperatures, making it harder for land life to thrive.
The tilt of a planet's axis is crucial, especially for fast-spinning planets, as it helps regulate seasonal temperature variations.
Being in the 'Goldilocks zone' (not too hot or cold) isn't enough; orbital and rotational factors also play a key role in making a planet truly habitable.
These findings help scientists refine the search for habitable exoplanets by considering more than just distance from the host star, focusing on orbital dynamics and planetary tilt.

Andhra woman becomes first Indian to complete Nasa program, to go to space in 2029
Dangeti Jahnavi from Palakollu in Andhra Pradesh's West Godavari district is set to travel to space in 2029. A graduate in Electronics and Communication Engineering, Jahnavi holds the distinction of being the first Indian to successfully complete NASA's prestigious International Air and Space has been selected to travel to the Titan's Orbital Port Space Station, a US-based project slated for inauguration in the next four space enthusiast completed her undergraduate studies at Lovely Professional University in Punjab, after finishing her Intermediate education in her hometown of Palakollu. Her parents, Srinivas and Padmasri, currently reside in Kuwait for work. Jahnavi is known for her active engagement in the field of STEM education and space outreach. She has delivered talks for ISRO's educational programs and addressed students at premier institutions including National Institutes of Technology (NITs) across the country. She also regularly takes part in analog missions, deep-sea diving, and global conferences related to planetary science and sustainability in long-duration space contributions to the International Astronomical Search Collaboration led to a provisional asteroid discovery, based on data from the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). She was also the youngest foreign analog astronaut and the first Indian chosen for Space Iceland's geology the years, Jahnavi has been recognised with numerous accolades including the People's Choice Award at the NASA Space Apps Challenge and the ISRO World Space Week Young Achiever Award.- Ends IN THIS STORY#Andhra Pradesh

NASA captures crash site of Japanese ‘Resilience' lunar lander on the Moon
NASA's Lunar Reconnaissance Orbiter (LRO) has taken a clear image showing the crash site of Japan's Resilience moon lander, built by Tokyo-based company ispace. The lander tried to touch down on June 5, in the Mare Frigoris region of the Moon but lost contact during descent. The image captured by NASA shows a dark spot with a light ring around it, likely caused by the hard impact and moon dust due to the disturbance by the Japanese lander. This is ispace's second failed attempt to land on the Moon. The Resilience spacecraft was trying to land safely in Mare Frigoris, an area of the Moon that has been formed by ancient lava flows. But soon after starting its landing, ispace lost contact with the lander. Later, it was confirmed that the lander had crashed to the surface of the Moon. The image captured by NASA's LRO shows a dark spot (called regolith) where the spacecraft hit the Moon and disturbed its surface. The light ring around the crash site likely came from small particles spread out by the impact. Scientist Mark Robinson confirmed that the crash happened about 2.4 kilometres away from the planned landing spot. A small micro-rover named Tenacious, made by ispace's European team, was also lost in the crash. It also carried a small piece of artwork called 'Moonhouse' created by Swedish artist Mikael Genberg. The artwork was a tiny red-and-white model of a Swedish-style house, meant to represent human creativity and the idea of living on the Moon. This artwork was part of a symbolic mission that blended space exploration with art. Sadly, the rover crashed during its mission, and Moonhouse now lies amidst the wreckage. This was ispace's second failed Moon mission. Its first lander also crashed in April 2023. Despite these failures, ispace is still one of the few private companies working to explore the Moon. The crash shows how hard space travel is, especially on the Moon, where everything must work perfectly. While the crash is a setback, NASA's images of the site provide useful data to ispace to help understand what went wrong with its lunar lander. As both private companies and national space agencies plan more Moon missions, such information could be potentially important for learning, improving, and being prepared for future landings on the lunar surface.
