A joint analysis of the diffuse γ-ray and neutrino emissions in the Galaxy shows that there is a non-negligible leptonic component in the diffuse γ-ray emission below 100 TeV that is contributed by pulsar halos.]]>

<![CDATA[Modelling the impact of DART on the asteroid Dimorphos reveals its rubble-pile structure]]> https://www.nature.com/articles/s41550-024-02208-9 Nature Astronomy, Published online: 12 March 2024; doi:10.1038/s41550-024-02208-9

The successful impact of NASA’s DART on Dimorphos, the moon of asteroid Didymos, has been analysed using advanced numerical simulations. The results reveal the asteroid’s low surface cohesion and rubble-pile structure, similar to what has been observed on asteroids Ryugu and Bennu.]]>

JWST detections of Si, C and Fe absorption lines in a bright z = 9.31 galaxy with a two-component clump structure suggest that mergers contributed to the rapid build-up of mass and chemical enrichment soon after the Big Bang.]]>

Water molecules in Europa’s icy surface are split into hydrogen and oxygen by charged particle bombardment. NASA’s Juno spacecraft flew near Europa and constrained the production of oxygen in Europa’s surface ice, thus providing only a narrow range to support habitability in its subsurface ocean.]]>

Spectrally and spatially resolved ALMA observations of water vapour in the inner regions of the famous planet-forming disk around HL Tauri pave the way towards an observational characterization of planet formation at the water snowline.]]>

<![CDATA[Cosmic dust may have driven the geochemical origins of life on Earth]]> https://www.nature.com/articles/s41550-024-02213-y Nature Astronomy, Published online: 27 February 2024; doi:10.1038/s41550-024-02213-y

Cosmic dust contains all the elements needed for life but has previously been considered too rare to have acted as a ‘fertilizer’ for prebiotic chemistry. Now, using a combination of astrophysical and geological models, it is revealed that cosmic dust could have gently accumulated on the surface of early Earth in sufficient quantities to promote the chemical reactions that led to first life.]]>

Numerical simulations of the DART impact on asteroid Didymos’s moon Dimorphos highlight its rubble-pile nature with a low bulk density and boulder volume fraction. These results indicate that Dimorphos formed from reaccumulated material shed from Didymos via rotation or impact.]]>
