The accretion of new material during Pluto's formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day.
The ringless Mars we see today is probably an anomaly. We’re in between rings right now, and we’ve assumed that’s normal.
After months of perseverance, the team operating the instrument has succeeded in getting the Mole at least some distance into the ground. The Mole's job is to penetrate into the Martian soil, to a depth of 5m.
4 billion year old Nitrogen containing organic molecules has been discovered in Martian meteorites. This finding suggests a wet and organic-rich early Mars, which could have been habitable and favorable for life to start.
Scientists are still preparing for the crucial fly-by of Earth by the joint European–Japanese BepiColombo mission to Mercury on 10 April, despite COVID-19 quarantine.
Mercury, the closest planet to the Sun, is one of the last places we think about when considering the potential for life in the solar system. New research suggests the planet's interior once contained the basic ingredients for life.
By going over old data collected by the Voyager 2 spacecraft in 1986, two scientists at NASA’s Goddard Space Flight Center have made the startling discovery that Uranus’ atmosphere is gradually escaping into space.
The planet’s extreme daytime heat combined with the super-cold (minus 200-degree Celsius) temperatures in the permanently shadowed craters might be acting like an “ice-making chemistry lab.”
The molecules were extracted by the Curiosity rover from a mudstone section of the Gale Crater. Scientists have concluded that we can't rule out those molecules actually have a biological origin.
NASA has selected four possible planetary science missions for further evaluation, two focused on Venus, one on Jupiter's volcanic moon Io and one on Neptune's icy moon Triton. Final selections will be made next year.
During the day, a thin layer of nitrogen ice warms and turns into vapor. At night, the vapor condenses and once again forms ice. Each sequence is like a heartbeat, pumping nitrogen winds around the dwarf planet.
Hygiea is located in the main asteroid belt between Mars and Jupiter and is the fourth largest object in the main asteroid belt. Now, a new telescopic survey suggests Hygiea is a dwarf planet, due to its surprisingly spherical shape.
According to an international team of scientists, the lake that was present in Gale Crater over 3 billion years ago underwent a drying episode, potentially linked to the global drying of Mars.
A team of German scientists recently examined data gathered by the Cassini orbiter around Enceladus’ southern polar region and found was evidence of organic signatures that could be the building blocks for amino acids.
According to new study by a team of NASA scientists, Venus would have been able to maintain stable temperatures – from a low of 20 °C (68 °F) to a high of 50 °C (122 °F) – for about three billion years.
