6 天之前 · A 20-Year Journey of Discovery. Confirming the presence of HD 20794 d took years of patient research and advanced data analysis. Researchers combined two decades’ worth of observations from high-precision instruments such as ESPRESSO and HARPS.

2021年8月14日 · We’ve known for some time now our universe is expanding, and in recent years discovered this was happening considerably faster than we’d expected. Yet despite momentous innovations in telescope and satellite technology, it’s thought much of what’s out there in the cosmos lies beyond our line of sight — beyond the “observable universe”, as it’s called.

2023年11月30日 · In a groundbreaking discovery, astronomers using the James Webb Space Telescope have found that planets resembling Earth, complete with water, can form in the most unlikely places: regions of space with extreme conditions, drenched in harsh ultraviolet radiation from massive stars.

2024年11月9日 · In the past few decades, there has been an explosion in the number of extra-solar planets that have been discovered. As of April 1st, 2018, a total of 3,758 exoplanets have been confirmed in 2,808 systems, with 627 systems having more than one planet.

2025年1月24日 · A Universe in a Grapefruit. It might sound astonishing, but the visible universe—now so big that its farthest galaxies lie more than 13 billion light-years away—was once packed into a volume roughly the size of a grapefruit. At the very beginning, all matter and energy were crammed together, resulting in extremely high temperatures and densities.

2023年8月9日 · Mars' heart, another mystery. The same tech, RISE, has given hints about Mars' heart, its core. It seems the core is pretty large, roughly half the size of the whole planet! Plus, it's not a perfect ball; it has an odd shape that scientists are trying to understand better. As per usual with these types of discoveries, the curtain rises on …

2024年2月15日 · Eating more processed red meat increases the risk of cognitive decline and dementia, according to a study published in the peer-reviewed science journal Neurology.

2024年7月10日 · The Elusive Intermediate-Mass Black Holes. Black holes are known to exist in a range of sizes, from stellar black holes, a few times the mass of our Sun, to supermassive black holes that are millions or billions of times more massive.. The current theory of galaxy evolution suggests that the earliest galaxies should have had intermediate-sized black holes at their centres, which grew over time.

2024年9月18日 · George Djorgovski, co-author of the study and a professor of astronomy and data science at Caltech explained that astronomers believe that galaxies and their central black holes co-evolve, and one key aspect of this is that jets can spread huge amounts of energy that affect the growth of their host galaxies and other galaxies near them."This discovery shows that their effects can extend much ...
