Itokawa<\/strong>
\nL’ast\u00e9ro\u00efde Itokawa n’a pas une densit\u00e9 uniforme – certaines parties sont plus denses, d’autres moins denses. C’est ce que sugg\u00e8re une \u00e9tude bas\u00e9e sur les changements de sa rotation avec le temps.

Bombardement martien<\/strong>
\nUn joli crat\u00e8re de 30 m de diam\u00e8tre s’est form\u00e9 sur Mars il y a quelques mois. Il en appara\u00eet environ deux cents de belle taille chaque ann\u00e9e, mais celui-ci est particuli\u00e8rement impressionnant.

Trous noirs<\/strong>
\nLes trous noirs cr\u00e9\u00e9s par les premi\u00e8res \u00e9toiles de l’Univers vivaient parfois en couple. En avalant la mati\u00e8re de leur compagnons, ils deviennent de brillantes sources de rayons X, capables de r\u00e9chauffer les environs. Toutefois, ils ont mis plus de temps \u00e0 r\u00e9chauffer l’Univers jeune qu’on ne le pensait.

Supernovae<\/strong>
\nDes mod\u00e8les de plus en plus r\u00e9alistes de supernovae permettent d’expliquer les abondances en \u00e9l\u00e9ments lourds des galaxies.
