Spacetime Symmetries
Spacetime symmetries are features of spacetime that can be described as exhibiting some form of symmetry. The role of symmetry in physics is important in simplifying solutions to many problems. Spacetime symmetries are used in the study of exact solutions of Einstein's field equations of general relativity. Spacetime symmetries are distinguished from internal symmetries.

PSR B1620-26 B
PSR B1620-26 b is an extrasolar planet located approximately 12,400 light-years away from Earth in the constellation of Scorpius. It bears the unofficial nicknames "Methuselah" and "the Genesis planet" due to its extreme age and a few popular sources refer to this object as "PSR B1620-26 c" (see below for discussion). The planet is in a circumbinary orbit around the two stars of PSR B1620-26 (which are a pulsar (PSR B1620-26 A) and a white dwarf (WD B1620-26)) and is the first circumbinary planet ever confirmed. It is also the first planet found in a globular cluster. The planet is one of the oldest known extrasolar planets, believed to be about 12.7 billion years old.

Emotive Internet
Emotive Internet (also Emotive Web, Emotional Internet) is a conceptualization of the Internet as an emergent emotional public space, such as how it serves as a space for the social sharing of emotions. It can also denote the quality of the Internet that allows it to be used to communicate in an emotive fashion or with emotional intent. Since it is an expressive medium, it also enables users to construct and represent their identities online. This is evident in the way emotional responses have been integrated in online communication and interactions. The concept is also linked to emotional analytics and emotion-sensing applications, particularly those technologies that power the Internet of Things (IoTs) - the smart home devices that have the capability to store and process the user's emotional profile to deliver services.
