Japan-led mission uncovers asteroid with all 5 ‘letters’ of DNA, breakthrough for understanding life’s origins
Analysis of samples from the asteroid Ryugu has revealed all five nucleobases essential to DNA and RNA, strengthening evidence that life’s chemical building blocks are widespread in space. While not proof of extraterrestrial life, the finding suggests asteroids could have delivered key ingredients to early Earth, offering new insight into how life’s fundamental chemistry may emerge across the universe.
Watch: How Moon's gravity will help Artemis II return to Earth
NASA's Artemis II mission achieved a pivotal moment with the Orion spacecraft's main engine ignition, propelling astronauts towards the Moon. This crucial six-minute burn, generating immense thrust, set a 'free return trajectory' and marked humanity's return to deep space since 1972.
10 historical signs that suggest aliens exist
There are historical and celestial anomalies in human history that make us question what we thought we knew about how technology and the stars interacted in the past. The Giza Plateau's unmatched geodetic accuracy and the strange ‘out-of-place’ artefacts like the Antikythera Mechanism are just two examples of unexplained things from around the world. Mainstream academia often says that these kinds of accomplishments are due to lost human creativity, but the fact that these sites are so complicated logistically and mathematically lends credence to the paleocontact hypothesis.
From cookies to green tea: What Nasa Artemis II astronauts have in their moon mission menu
As Artemis II launches, astronauts are fueled by a meticulously planned food supply designed for health and energy during their lunar journey. The 189 unique menu items, including beverages, meals, and treats, are selected for shelf-stability and ease of consumption in microgravity, ensuring crew well-being for this historic mission.
First time since 1972, humans leave Earth orbit: Artemis II astronauts head for the Moon; what comes next?
Humans have once again ventured beyond Earth's orbit as NASA's Artemis II mission successfully propelled its crew towards the Moon. This historic flight, the first since 1972, carries a diverse crew on a lunar flyby, marking a significant step in humanity's return to deep space exploration and paving the way for future lunar missions.
Artemis II astronauts manually pilot Orion: Nasa video shows spacecraft heading towards Moon
Nasa's Orion spacecraft has successfully separated from its rocket during the Artemis II mission. Astronauts are now conducting proximity operations tests. This historic journey marks humanity's return to lunar space after over 50 years. The mission, lasting about 10 days, will see the crew fly around the Moon and capture images of its surface.
Why Artemis II will not land on the Moon even though NASA did it 50 years ago
NASA's Artemis II mission, a 10-day lunar flyby, marks humanity's return to deep space after 50 years. This crucial test flight validates the Orion spacecraft and Space Launch System rocket for future landings. Unlike Apollo's race against time, Artemis prioritizes long-term lunar presence and eventual Mars missions, emphasizing safety and sustainability over speed.
10 ‘superpowers’ women possess that are biologically impossible for men
The woman's body is often thought of as simply an average body. However, the more we learn about evolutionary biology, the more we understand that the women’s genome has been specifically adapted for a different form of highly efficient survival. From how the brain interprets sensory information all the way down to having two sets of immune system genes on its X chromosome (which accounts for the fact that females, on average, have a higher immunity to disease than males), a great number of characteristics that make females biologically unique do not get recognised. Here are some examples of physiological accomplishments performed by women with much greater levels of efficiency than men.
13 Full moons of 2026: Here are their dates and names
There is something quietly magical about a full moon. It happens every month without fail, yet it never feels like an ordinary occurrence. In 2026, the night sky will feature not twelve, but thirteen full moons. These have been given various names based on different factors like seasons, folklore, and memory. From the icy stillness of January's Wolf Moon to December's Cold Moon, this photostory will take you through all of 2026's full moons, combining astronomy and folklore, and encourage you to look up at the sky above.Astronomical records have confirmed that there will be thirteen full moons in 2026, including a rare blue moon in May. These have been given different names based on various factors like seasons and folklore.
