When you throw a ball at a wall, you can be sure it will bounce back at you.
You would be extremely surprised if the ball suddenly appeared on the other side of the wall. In quantum mechanics this type of phenomenon is called tunnelling and is exactly the type of phenomenon that has given it a reputation for being bizarre and unintuitive.
The 2025 #NobelPrize laureates in physics John Clarke, Michel H. Devoret and John M. Martinis, used a series of experiments to demonstrate that the bizarre properties of the quantum world can be made concrete in a system big enough to be held in the hand. Their superconducting electrical system could tunnel from one state to another, as if it were passing straight through a wall. They also showed that the system absorbed and emitted energy in doses of specific sizes, just as predicted by quantum mechanics.
After +3 years of data reduction, statistics, modelling, writing, submitting, etc, we can now better understand how protoplanetary disks evolve thanks to the AGEPRO ALMA (@almaobs) Large Program.

Amazing work led by @MrAsghaloth on the most promising candidate for planet formation in the substellar regime! Please take a look at the paper here: 🔗 https://t.co/u9uVtvlmA7
Today I get to share the most important paper of my career.
This letter has just been accepted, and it’s been over 6 years in the making — an idea that started during my PhD and has been with me ever since.
A dream come true.
🧵[1/6]
📡 Take a look to the excellent work lead by @MrAsghaloth (in which I have the honour to participate), where a gap-ring structure was observed in the disk around a brown dwarf
🪐 This is a remarkable discovery related to planet formation in the sub-stellar regime.
Aprobación unánime de proyecto de acuerdo de 40 senadoras y senadores que solicitamos al Presidente de la República para que utilice las facultades que tiene para proteger el patrimonio astronómico nacional y permitir que Chile siga desarrollando ciencia para toda la humanidad.
Take a look to my new paper:

Gente !! Perdí mi billetera en el @AeroPuertoMontt entre los gate 4y5 hoy a eso de las 3pm si alguien la encontró por favor avíseme estaré muy agradecida y prometo ir donde sea a buscarla y se llevará regalitos astronómicos 🫶
Hydrated ammonium magnesium-phosphorus-rich (‘HAMP’) grains have been discovered in Ryugu samples. They may have been a key source of phosphorus and nitrogen in early terrestrial water reservoirs. Pilorget et al.: https://t.co/0sZDvVCIDY / https://t.co/xrLYOJvZNd
Les dejamos invitados al lanzamiento del libro "Amor Microbiano" de nuestra socia Dra. @criordor. Este miércoles 25 de septiembre a las 18:30 hrs en Paseo Bulnes 152 con la participación de la comunicadora científica @Mrojas_Abalos🦠💘
“Los datos son muy reveladores y contundentes, y demuestran que el capital humano está, y la voluntad, interés y energías por retribuir efectivamente a Chile también están. Sólo falta la voluntad del administrador del Estado para cambiar el malogrado decreto…” @CARLOSZAMO90707
Take a look to my new paper:
"Constraints on the physical origin of large cavities in transition disks from multi-wavelength dust continuum emission",
where we suggest possible origins for the large cavities of CQTau, UXTau A, LkCa15, RXJ1615, SR24S, and DMTau.
Agradecida de ser recibid@s por @Presidencia_cl y @min_ciencia Las comunidades de investigador@s pueden lograr grandes cosas cuando trabajan en equipo y @sochias_cl hizo una gran labor uniendo instituciones a lo largo del país. Se vienen 6 años de trabajo para la @IAU_org 2030✨
Hoy en el Palacio de La Moneda, la Ministra @AisenEtcheverry acompañó al Presidente @GabrielBoric en la reunión con la directiva de @sochias_cl , tras la elección de Chile como sede de la asamblea de la @IAU_org en 2030.
