  Quark matter both in terrestrial experiment and in astrophysics is briefly
reviewed. Astrophysical quark matter could appear in the early Universe, in
compact stars, and as cosmic rays. Emphasis is put on quark star as the nature
of pulsars. Possible astrophysical implications of experiment-discovered sQGP
are also concisely discussed.
