Shining star! Kate Beckinsale displays cleavage in a VERY plunging gown as she arrives at party held at NASA's Hangar One
Kate Beckinsale was surrounded by Hollywood royalty and some of the brightest minds in science.
Yet the 41-year-old managed to shine all her own in a low-cut dress that featured a very daring neckline that dipped close to her waistline at the Breakthrough Prize Awards on Sunday.
The starlet looked her absolute best in the artistically-themed frock as she completed her turn on the red carpet of the event, which was located at Hangar One, a former shelter for NASA airships, in Mountain View, California.

She's a shining star! Kate Beckinsale wowed in a plunging gown as she completed her turn on the red carpet at the Breakthrough Prize Awards at Mountain View, California on Sunday evening
The star's bold look, though modest in it's hem length, hugged Kate's splendid curves while providing a peek of her slender waistline with a strategically placed cut-out above her hips.
With her honey-hued locks slicked back into a taut and no-fuss ponytail, Kate's flawless and youthful face was put on full show.
The actress emphasized her youthful complexion with a natural coat of bronzer blush, as well as a matching application of eyeshadow.
Going for the wow factor: As well as her cleavage, Kate ensured her slender and toned arms were put on show, while Cameron Diaz opted for a more understated look

Having accessorised with just a pair of teardrop earrings, the Serendipity starlet ensured little jewellery distracted from one of her most prized features: her toned and slender arms.
While Kate wowed in her plunging and form-fitting frock, Cameron Diaz opted to shine in an understated two-piece look.
The 42-year-old donned a sleeveless deep blue top that was tucked into a knee-length black pencil skirt.
