The Formation of Glycolamide on Interstellar Ices
For decades, scientists have searched interstellar space for the chemical seeds of life. In this issue of ACS Central Science, Kaiser and co-workers (1) offer a striking advance in that […]
JWST Unveils A High Mean Molecular Weight Atmosphere For Mini-Neptune TOI-1130b: Evidence For Formation Beyond The Water Ice Line
We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R⊕, 19.8 M⊕, Teq∼825 K). It is part of a rare and unique […]
Did Impacts From Meteors Help Start Life On Earth?
Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells could take shape, according to research integrated by a recent Rutgers University […]
Early Life On Earth Relied On A Surprisingly Scarce Metal: Molybdenum
A new study from researchers at the University of Wisconsin–Madison shows that 3.4 billion years ago, life on Earth relied on a metal called molybdenum, despite its limited availability at […]
Observations Of Atmospheric Helium And Oxygen With SPHEREx
We present measurements of near-infrared (NIR) terrestrial airglow produced by helium and oxygen in the exosphere as observed by SPHEREx. Using eight months of survey data obtained from a 680 […]
The Atmosphere Of The Warm Neptune GJ 436 b Probed With ESPRESSO
Aims. We aim to identify the presence of atomic and molecular species in the upper atmosphere of the warm Neptune-sized transiting planet GJ 436 b, which has a radiative equilibrium […]
Trans-Neptunian Object (612533) 2002 XV93 Has An Atmosphere – But Shouldn’t
A team of professional and amateur Japanese astronomers found evidence for a thin atmosphere around a small body in the outer Solar System. The object is so small that it […]
Moon Record Analysis Challenges Impact Origin Of Earth’s Water
A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study argues that the […]
