Physicist Cosimo Bambi proposes a century-long mission to send a gram-scale laser-driven probe to a black hole 20 light-years away to test Einstein's theory, facing technological and financial challenges but promising groundbreaking insights into black holes and fundamental physics.
The heliosphere, the vast region of space influenced by the sun, acts as a shield against cosmic rays and interstellar particles. Scientists aim to understand its shape and interactions with the interstellar medium, but current probes like Voyager lack the necessary instruments. NASA is considering launching a new interstellar probe to study the heliosphere from the outside, which could provide invaluable data on its structure and behavior.
Scientists are exploring mission concepts for an interstellar probe to travel beyond the sun's heliosphere and understand its boundaries and shape. A study recommends an exit route through the heliosphere's tail end to maximize scientific measurements. The mission aims to collect samples from the local interstellar medium and provide unprecedented insights into the heliosphere's interaction with the interstellar environment. This research challenges previous assumptions about the optimal trajectory for the interstellar probe and emphasizes the importance of additional measurements outside the heliosphere to determine its shape and boundaries.
