New Technique Reveals Centuries of Secrets in Locked Letters

M.I.T. researchers have devised a virtual-reality technique that lets them read old letters that were mailed not in envelopes but in the writing paper itself after being folded into elaborate enclosures. From a report: In 1587, hours before her beheading, Mary, Queen of Scots, sent a letter to her brother-in-law Henry III, King of France. But she didn’t just sign it…

Astronomers identify faint radio-jets in the galaxy cluster CLJ1449+0856

Using ground-based facilities and space telescopes, an international team of astronomers has conducted multiwavelength observations of a galaxy cluster known as CLJ1449+0856. The observational campaign detected multiple faint radio-jets, what could shed more light on the nature of this cluster. The finding is reported in a paper published February 23 on the arXiv pre-print server. Source: https://phys.org/news/2021-03-astronomers-faint-radio-jets-galaxy-cluster.html…
