مايو

  • اكتشاف HR 6819، أول ثقب أسود قريب من الأرض ضمن منظومة النجوم يمكن رؤيته بالعين المجردة. أفادت دراسة نُشرت في مايو 2020 الجرم يحتوي على ثقب أسود، مما يجعله أقرب ثقب أسود معروف، وأول ثقب أسود يقع في منظومة نجمية يمكن رؤيته بالعين المجردة. بسبب موقعه في السماء، يمكن رؤيته فقد جنوب خط العرض 33°N.

سبتمبر

أكتوبر

في 20 أكتوبر 2020، تمكن فريق علماء ألمان، من جامعة گوت في فرانكفورت، ومعهد ماكس پلانك في برلين، من تسجيل أقصر فاصل زمني على الإطلاق، وهو ما ساعدهم على أن يقيسوا المدة التي يستغرقها الضوء حتى يعبر جزيئاً واحداً فقط من الهيدروجين. استغرق هذا هذا الفاصل القصير للغاية، 247 زپتو/ثانية، الزپتو/ثانية يعادل 1/ترليون مليار من الثانية. ويرى خبراء أن هذا الاكتشاف يتوّج جهوداً عالمية حثيثة من أجل قياس فواصل زمنية متناهية القصر في الفيزياء، ولم يجر تسجيلها من قبل.[33]
