Scientists observe violent collisions around young star Fomalhaut, detecting the aftermath of two powerful collisions over a 20-year period. The collided objects are estimated to be at least 60 kilometers across and may have formed planets.
Experimental tests demonstrate that interactions between magma oceans and primitive atmospheres during early years can produce significant amounts of water. This process has major implications for the physical and chemical properties of planets' interiors, with potential effects on core development and atmospheric composition.
Astronomers discovered a greedy white dwarf star consuming its closest celestial companion at an unprecedented rate. The study found that the super-dense white dwarf is burning brightly due to the mass transfer between the two stars, potentially leading to a massive explosion visible from Earth.
Researchers use NASA's James Webb Space Telescope to investigate a protoplanetary disk around a young star in the Lobster Nebula. They found sufficient solid material to potentially form at least 10 rocky planets and detected various molecules that contribute to planetary atmospheres.
A new study using NASA's James Webb Space Telescope has confirmed the presence of proplyds around brown dwarfs in the Orion Nebula. The team discovered 20 cool objects that are too small and cool to undergo hydrogen fusion, with two faint proplyds detected by Hubble previously.
A study of the Orion Nebula reveals that massive stars play a crucial role in shaping planetary systems. The intense ultraviolet radiation from these stars can either facilitate or hinder planet formation, depending on the mass of the star at the system's center.
Researchers have discovered that primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. This suggests that the Solar System was formed from a 'poorly mixed cake batter' of materials, with some planets receiving a unique blend of elements from distant sources.
Scientists have made new discoveries about the early solar system using meteorite glass beads. By analyzing the isotopic compositions of elements in these beads, researchers were able to determine that massive shockwaves passing through the nebula caused the extreme heating and cooling necessary for chondrule formation.
